PURPOSE:To prevent crystallization of a photosensitive body without decreasing the electrifying power of a photosensitive body by heavy doping by forming the noble metal element of the I group of periodic table so as to exist on at least the outside surface of an agitating device for a developer. CONSTITUTION:This device is provided with an Al drum 101 having a selenium photosensitive layer 102 contg. 8atom% tellurium and having 57mu thickness, a stationary magnetic drum 103 having a main magnet 104 and auxiliary magnets 105, 106, a scraper 108 of a sleeve 107 turning around the drum 103, an agitating device 109, etc. The device 109 consists of four vanes made of plastic intersecting orthogonally to each other and is coated with 50mg copper stearate on the outside surface for 150cm<2> surface area. The copper stearate is one of the noble metal elements of the I group of periodic table. |
