Claim 4

An image forming apparatus according to claim 2 wherein said processing means include original exposure means for exposing an original image, and said control means controls said original exposure means to expose the original image during the processing time to said other ones of the multi-fed recording media.

Claim 5

An image forming apparatus according to claim 2 or 3 wherein said control means inhibits the first feed of the recording medium from said container after the detection of the multi-feed.

Claim 6

An image forming apparatus according to claim 1 wherein said processing means include a charge for charging a photosensitive member, and said control means disables said charger during the processing time to said other ones of the multi-fed recording media.

Claim 7

An image forming apparatus comprising: a container for storing sheets of recording media; image forming means for forming images on said recording media fed from said container; feed means for feeding said sheets from said container to a predetermined station, said feed means including a feed path extending from said container to said predetermined station and separation means for separating multi-fed sheets from each other; a detection means for detecting multi-fed sheets at a predetermined position along said feed path; and control means, responsive to the detection of multi-fed sheets by said detection means, for feeding one of the multi-fed sheets separated by said separation means to said image forming means, and collecting the remainder of the multi-fed sheets at a specified area.

Claim 8

An image forming apparatus comprising: a container for storing sheets of recording media; image forming means for forming images on said recording media fed from said container; feed means for feeding said sheets from said container to a predetermined station, said feed means including a feed path extending from said container to said predetermined station and separation means for separating multi-fed sheets from each other; a detection means for detecting multi-fed sheets at a predetermined position along said feed path; and control means, responsive to the detection of multi-fed sheets by said detection means, for feeding one of the multi-fed sheets separated by said separation means to said image forming means, and collecting the remainder of the multi-fed sheets at a specified area.

Claim 9

An image forming apparatus according to claim 6 wherein said specified area is along said feed path.

Claim 10

An image forming apparatus according to claim 6 wherein said specified area is a multi-fed sheet container located outside said feed path.

Claim 11

An image forming apparatus according to claim 6 further comprising means for displaying a multi-feed of recording media.

Claim 12

An image forming apparatus comprising: a container for storing recording media; a plurality of processing means for forming images on recording media fed from said container; detection means for detecting a multi-feed of the recordng media fed from said container; separation means for separating the multi-fed recording media one from others; and control means for controlling said processing means, in response to the detection of a multi-feed by said detection means, to form an image on one of the multi-fed recording media separated by said separation means and form no image on the other ones of the multi-fed recording media, wherein said processing means includes exposure means for exposing the image while said exposure means is reciprocated and said control means inhibits the reciprocation of said exposure means for said other ones of the multi-fed recording media.

Claim 13

An image forming apparatus comprising: a container for storing recording media; a plurality of processing means for forming images on recording media fed from said container; detection means for detecting a multi-feed of the recordng media fed from said container; separation means for separating the multi-fed recording media one from others; and control means for controlling said processing means, in response to the detection of a multi-feed by said detection means, to form an image on one of the multi-fed recording media separated by said separation means and form no image on the other ones of the multi-fed recording media, wherein said processing means includes exposure means for exposing the image while said exposure means is reciprocated and said control means inhibits the reciprocation of said exposure means for said other ones of the multi-fed recording media.

Claim 14

An image forming apparatus comprising: a container for storing recording media; a plurality of processing means for forming images on recording media fed from said container; detection means for detecting a multi-feed of the recording media fed from said container; separation means for separating the multi-fed recording media one from others; and control means for controlling said processing means, in response to the detection of a multi-feed by said detection means, to form an image on one of the multi-fed recording media separated by said separation means and form no image on the other ones of the multi-fed recording media, wherein said processing means includes exposure means for exposing the image while said exposure means is reciprocated and said control means inhibits the reciprocation of said exposure means for said other ones of the multi-fed recording media and delays a feed timing of recording media from said container after the detection of a multi-feed for a predetermined time period.

Claim 15

An image forming apparatus comprising: a container for storing recording media; a plurality of processing means for forming images on recording media fed from said container; detection means for detecting a multi-feed of the recording media fed from said container; separation means for separating the multi-fed recording media one from others; and control means for controlling said processing means, in response to the detection of a multi-feed by said detection means, to form an image on one of the multi-fed recording media separated by said separation means and form no image on the other ones of the multi-fed recording media, wherein said processing means includes exposure means for exposing the image while said exposure means is reciprocated and said control means inhibits the reciprocation of said exposure means for said other ones of the multi-fed recording media and delays a feed timing of recording media from said container after the detection of a multi-feed for a predetermined time period.
