Process cartridge, electrophotographic apparatus and image forming method

摘要

A process cartridge detachably mountable to the electrophotographic apparatus main body, integrally including an electrophotographic photosensitive member to carry a toner image; an intermediate transfer belt having a contact part with the photosensitive member; primary transfer member to primarily transfer the toner image from the photosensitive member to the intermediate transfer belt; and electric charge member to give electric charges in polarity opposite to the polarity of the toner at the time of the primary transfer to the toner on the intermediate transfer belt to return the toner on the intermediate transfer belt to the photosensitive member at the contact part to clean the intermediate transfer belt, wherein the intermediate transfer belt has an average glossiness of 30 to 90; glossiness deviation within 10; average film thickness of 40 to 200 mum; and film thickness unevenness within ±20% relative to the average film thickness. Also, an electrophotographic apparatus having the process cartridge and an image forming method using the electrophotographic apparatus are disclosed.
