摘要： A process cartridge is disclosed integrally supporting an electrophotographic photosensitive member, an intermediate transfer belt, a primary-transfer means for transferring a toner image primarily from the electrophotographic photosensitive member to the intermediate transfer belt, a charge-providing means for providing the toner on the intermediate transfer belt with electric charges having a polarity reverse to the polarity the toner has at the time of the primary transfer and returning the toner on the intermediate transfer belt to the electrophotographic photosensitive member at the contact zone to clean the intermediate transfer belt, and an electrophotographic-photosensitive-member cleaning means. The process cartridge is dividable into an electrophotographic photosensitive member unit and an intermediate transfer belt unit and has a joining means which joins the two units. The peripheral length and average thickness of the intermediate transfer belt and the diameter of at least one of rollers over and around which the intermediate transfer belt is placed satisfy specific conditions. Also disclosed are an electrophotographic apparatus having this process cartridge, and an image-forming method making use of the electrophotographic apparatus.
