Abstract
Abstract In a recording apparatus, a developing agent image corresponding to an image information in accordance with data input through a data controller is formed on the surface of a photosensitive body by a laser scanner. The developing agent image is transferred to a paper sheet by a transfer charger, and the surface of the photosensitive body after a transfer operation is cleaned by a cleaning blade of a cleaning device. The recording apparatus comprises a developing agent applying mechanism which applies the developing agent to the surface of the photosensitive body, and which is operative when the laser scanner is not operated by a prescribed time.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
211 words
A recording apparatus comprising: an image carrier; input means for receiving data associated with image information to be recorded; image forming means including charging means for charging a surface of said image carrier, exposure means for exposing the surface of said image carrier charged by said charging means to form a latent image corresponding to the image information on the surface of said image carrier, and developing means for developing the latent image formed on the surface of said image carrier with a developing agent to form a developing agent image; transfer means for transferring the developing agent image formed on the surface of said image carrier by said developing means to a recording medium; cleaning means for cleaning the surface of said image carrier after a transfer operation by said transfer means, said cleaning means comprising a cleaning blade contacting the surface of said image carrier so as to remove residual developing agent after the transfer operation; means for controlling said input means, said image forming means, said transfer means and said cleaning means; and wherein said developing means is operated to apply the developing agent to the surface of said image carrier after a predetermined time from when said image forming means receives no signal from said input means.
Claim 2
Dependent Claim
211 words
A recording apparatus comprising: an image carrier; input means for receiving data associated with image information to be recorded; image forming means including charging means for charging a surface of said image carrier, exposure means for exposing the surface of said image carrier charged by said charging means to form a latent image corresponding to the image information on the surface of said image carrier, and developing means for developing the latent image formed on the surface of said image carrier with a developing agent to form a developing agent image; transfer means for transferring the developing agent image formed on the surface of said image carrier by said developing means to a recording medium; cleaning means for cleaning the surface of said image carrier after a transfer operation by said transfer means, said cleaning means comprising a cleaning blade contacting the surface of said image carrier so as to remove residual developing agent after the transfer operation; means for controlling said input means, said image forming means, said transfer means and said cleaning means; and wherein said developing means is operated to apply the developing agent to the surface of said image carrier after a predetermined time from when said image forming means receives no signal from said input means.
