摘要： An electrophotographic method which uses a single-layer organic photosensitive material drum having a single organic photosensitive layer of a thickness of not smaller than 25 &mgr;m formed on an electrically conducting blank tube with a surface roughness Ra of not larger than 0.6 &mgr;m and rotates the photosensitive material drum at a peripheral speed of not smaller than 400 mm/sec, in order to execute an image-forming processing that includes electric charging, exposure to image-bearing light, developing, transfer, cleaning by a blade and removal of electric charge. Though the photosensitive material drum rotates at a high speed and a large frictional force is exerted on the cleaning blade, damage to the blade is effectively suppressed, and image is stably formed for extended periods of time without permitting the cleaning to become defective.

摘要： With the object of providing an imaging method that eliminates the occurrence of transfer ghosts, saves space and lowers costs, and by which image density irregularities do not arise, an imaging method utilized in a reverse-transfer system is disclosed. The reverse-transfer system is provided with, in order going round a photosensitive conductor 1, at least a main-charging stage 2, an exposure stage 3, a reverse-developing stage 4, a transfer stage 5, a separation stage 6 and a charge-stripping stage 7. The separation stage 6 applies a separation shift-bias voltage to the photosensitive conductor 1 surface. The separation shift-bias voltage is 1 kV or more, and is of the same polarity as that of the main-charging voltage that the main-charging stage 2 applies to the photosensitive conductor 1 surface. Making the separation shift-bias voltage 1 kV or more prevents transfer ghosts, and obtains images with a satisfactory absence of image density irregularities.
