Abstract
For stably obtaining high-quality images with good cleaning properties, with neither occurrence of uneven scraping of a surface layer of a light receiving member nor fusion of a toner, and without occurrence of an image defect even without provision of a heater, the wear loss of the surface layer of a non-monocrystalline hydrogenated carbon film is made not less than 1 .ANG./10,000 sheets nor more than 10 .ANG./10,000 sheets after completion of copying processes of A4-size transfer sheets, each copying process including developing an image on a light receiving member with a developer having an average grain diameter of 5 to 8 .mu.m, then transferring the developer image onto a transfer medium, and thereafter scrape-cleaning the surface of the light receiving member with an elastic rubber blade having the hardness of not less than 70 nor more than 80.
