Abstract

PURPOSE:To obtain a laminated photoreceptor superior in sensitivity and color reproductivity, by adding a specified disazo pigment to a charge generating layer and a specified divinylbenzene compound to a charge transfer layer. CONSTITUTION:The charge generating layer of a laminated type photoreceptor contains a disazo pigment represented by the general formula (1) in which A is phenyl, chlorophenyl, nitrophenyl, 2,5-dichlorophenyl, 2-methyl-5-chlorophenyl, or 2-methyl-4-chlorophenyl. The charge transfer layer contains a divinylbenzene compound represented by the general formula (2) in which R is carbazolyl, pyridyl, thenyl, indolyl, furyl, or phenyl, styryl, naphthyl, anthryl optionally substituted by dialkylamino, alkyl, alkoxyl, carboxyl or its ester, halogen, cyano, aralkylamino, amino, hydroxyl, nitro, or acetylamino group.
