Electrophotographic process and apparatus simultaneously effecting image exposure and developing steps to opposite sides of photosensitive member. |
摘要 |
An electrophotographic process in which image information exposure step and a developing step are substantially simultaneously carried out to opposite sides of a photosensitive member includes preparing an electrophotographic photosensitive member having a conductive base layer transmitting light and a photosensitive layer thereon; exposing the conductive base side of the photosensitive member to light information; rubbing an opposite side of the photosensitive member with a developer supplied with a developing bias voltage of the same polarity as the polarity of the developer in a region including an upstream side and a downstream side of an image exposure region of the photosensitive member; wherein an absolute value of a sum of a triboelectric charge potential provided on a surface of the photosensitive member by rubbing between the developer and the photosensitive member, and a surface potential of the photosensitive member provided by application of the developing bias upstream of the image exposure region, is larger than an absolute value of the developing bias. <IMAGE> |
