Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR
Document Type and Number:
Japanese Patent JPH1195459
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve oil resistance and to prevent optical fatigue as well as to reduce the coefft. of friction of the surface of a photosensitive layer without deteriorating superior electrophotographic characteristics by incorporating a specified polycarbonate copolymer as a bonding resin and a specified amine compd. as an electric charge transferring agent into the photosensitive layer. SOLUTION: The electrophotographic photoreceptor has a photosensitive layer contg. a polycarbonate copolymer contg. repeating units represented by formula I as a bonding resin and an amine compd. represented by formula II or the like as an electric charge transferring agent. In the formula I, R1 -R12 are each 1-6C alkyl or 6-12C arom. hydrocarbon, (a) to (c) are each an integer of 2-6 and (d) is an integer of 0-200. In the formula II, Z and R21 -R23 , are each H, halogen, 1-6C alkyl or alkoxy which may have a substituent, substd. amino or unsubstd. aryl.
