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 μm formed on an electrically conducting blank tube with a surface roughness Ra of not larger than 0.6 μm 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.
An electrophotographic method for forming image by subjecting a rotary photosensitive material drum to an image-forming process which includes main electric charging, exposure to image-bearing light, developing, transfer, cleaning and removal of electric charge, wherein:
An electrophotographic organic photosensitive material drum for a high-speed image-forming processing, comprising an electrically conductive blank tube which has a surface roughness Ra (JIS-B-0601) of not larger than 0.6 μm and has a single organic photosensitive layer of a thickness of not smaller than 25 μm formed thereon.
