Electrophotographic photoreceptor containing hydroquinone derivative. Suzuki, Yasuo (Ricoh Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 03163457 A2 15 Jul 1991 Heisei, 22 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: G03G005-05.Several reagents with their cas registry numbers 139615-09-1 and 25785-60-8 are used here. APPLICATION: JP 90-210787 9 Aug 1990. PRIORITY: JP 89-217985 24 Aug 1989. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) In an electrophotog. photoreceptor having a photosensitive layer contg. a charge-generating material and a charge-transporting material on an elec. conductive support, the photosensitive layer contains a hydroquinone deriv. [I; R1-R4 = H, halogen, (un)substituted alkyl, alkenyl, aryl, cycloalkyl, alkoxy, aryloxy, alkylthio, etc.]. The electrophotog. photoreceptor shows excellent stability against ozone, provides stable electrification without rise in residual potential during repeated use, and gives good images without background stain or redn. of image d. .
