Electrophotograhic plate by use of metal naphthalocyanine derivative.

摘要

Disclosed are an electrophotographic plate comprising a photoconductive layer containing an organic photoconductive substance on an electroconductive support, characterized in that said photoconductive layer has a film containing as the organic photoconductive substance a metal naphthalocyanine derivative represented by the formula (I): <CHEM> wherein M represents germanium or tin; L and L' each independently represent a halogen, a hydroxyl group, an alkyl group, an alkoxy group or a siloxy group of the formula R1R2R3SiO- (wherein R1, R2 and R3 each independently represent a hydrogen atom, an alkyl group, an alkoxy group or an aryl group), a metal naphthalocyanine derivative defined above and a process for producing the same.
