Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, ELECTROPHOTOGRAPHIC DEVICE EQUIPPED WITH THAT PHOTORECEPTOR AND PROCESS CARTRIDGE
Document Type and Number:
Japanese Patent JP3313980
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent cracks in a charge transfer layer even when a photoreceptor is not used for a long time by incorporating a specified arylamine compd. into a photosensitive layer.
SOLUTION: This photoreceptor consists of a base body and a photosensitive layer formed on the base body. The photosensitive layer contains an arylamine compd. expressed by formula. In formula, R1 is an alkyl group which may have substituents, aralkyl group which may have substituents, or aromatic hydrocarbon ring group which may have substituents, R2-R8 are hydrogen atoms, halogen atoms, alkyl groups which may have substituents, alkoxy groups which may have substituents, or amino groups which may have substituents, and Ar is an alkyl group which may have substituents, aromatic hydrocarbon ring group which may have substituents, or aromatic heteroring which may have substituents. Therefore, the obtd. photoreceptor has good sensitivity and stable electrophotographic characteristics are obtd. even when it is repeatedly used.
