Image transfer complementary apparatus for electrophotographic copying machine

Claim 2

An image transfer complementary apparatus for an electrophotographic copying machine of the type for electrically charging and exposing a recording element to form an electrically charged latent image, thereafter developing the latent image to form a toner image and transferring the toner image to a transfer sheet with a transfer electrode, comprising an image transfer sheet depressing member mounted adjacent to the image transfer sheet transporting passage defined between the recording element and the transfer electrode provided adjacent to the recording element, said member being positioned in the vicinity of the electrode for engaging the transfer sheet on the non-image receiving surface of the sheet to forcibly depress the image-receiving surface of the sheet onto the surface of the recording element, said sheet depressing member being a resilient depressing plate which has an end deformable in response to the movement of the image transfer sheet pass said plate.

Claim 3

The image transfer complementary apparatus according to claim 1, wherein said resilient depressing plate has a plurality of slits formed in said deformable end.

Claim 4

An image transfer complementary apparatus for an electrophotographic copying machine of the type for electrically charging and exposing a recording element to form an electrically charged latent image, thereafter developing the latent image to form a toner image and transferring the toner image to a transfer sheet with a transfer electrode, comprising an image transfer sheet depressing member which is mounted adjacent to the image transfer sheet transporting passage defined between said recording element and said transfer electrode provided adjacent to said recording element, the depressing member being movably disposed to be spaced from the surface of said recording element when the transfer sheet is not yet being transported to said passage, and to engage the non-image receiving surface of the transfer sheet when said sheet is being transported through said passage to forcibly depress the image-receiving surface of said sheet onto the surface of said recording element, said depressing member being a resilient plate having an end portion which is deformable in response to the movement of said sheet pass said plate.

Claim 5

An image transfer complementary apparatus for an electrophotographic copying machine of the type for electrically charging and exposing a recording element to form an electrically charged latent image, thereafter developing the latent image to form a toner image and transferring the toner image to a transfer sheet with a transfer electrode, comprising an image transfer sheet depressing member which is mounted adjacent to the image transfer sheet transporting passage defined between said recording element and said transfer electrode provided adjacent to said recording element, the depressing member being movably disposed to be spaced from the surface of said recording element when the transfer sheet is not yet being transported to said passage, and to engage the non-image receiving surface of the transfer sheet when said sheet is being transported through said passage to forcibly depress the image-receiving surface of said sheet onto the surface of said recording element, said depressing member being a resilient plate having an end portion which is deformable in response to the movement of said sheet pass said plate.

Claim 6

The image transfer complementary apparatus according to claim 3, wherein said deformable end portion of said plate is provided with a plurality of slits.

Claim 7

In an electrophotographic copying machine having means for providing a developed toner image on the surface of a recording element and means, having a discharge electrode, for electrostatically transferring, at a transfer zone, the developed toner image to a transfer sheet supplied to the transfer zone, the improvement comprising an image transfer complementary device including a depressing plate having an end portion extending adjacent the recording element, at least the end portion of said plate being adapted to press the transfer sheet, at a position upstream of the transfer zone, against the surface of the recording element and being deformable in response to movement of the transfer sheet.

Claim 8

In an electrophotographic copying machine having means for providing a developed toner image on the surface of a recording element and means, having a discharge electrode, for electrostatically transferring, at a transfer zone, the developed toner image to a transfer sheet supplied to the transfer zone, the improvement comprising an image transfer complementary device including a depressing plate having an end portion extending adjacent the recording element, at least the end portion of said plate being adapted to press the transfer sheet, at a position upstream of the transfer zone, against the surface of the recording element and being deformable in response to movement of the transfer sheet.
