子写真装置において、上記電子写真感光体上のス
リツト露光部と像露光光路とを含む領域内であつ
て、且つ像露光の光路を妨げない位置に像露光と
は別の露光を上記感光体に施す光源を設けると共
に、該光源が所定の領域のみを照明するよう露光
の一部を遮る遮光部材を設け、少なくとも上記遮
光部材を常に像露光を妨げない位置に移動させる
手段を設けたことを特徴とする電子写真装置。 In an electrophotographic apparatus that slit-exposes an original image onto an electrophotographic photoreceptor, the image is placed in a region on the electrophotographic photoreceptor that includes a slit exposure section and an image exposure optical path, and at a position that does not obstruct the image exposure optical path. A light source for exposing the photoreceptor to light different from exposure is provided, and a light shielding member is provided for blocking part of the exposure so that the light source illuminates only a predetermined area, and at least the light shielding member does not always interfere with image exposure. 1. An electrophotographic device characterized by being provided with means for moving the device to a certain position.
