ABSTRACT:
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): ##STR1## 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 R.sub.1 R.sub.2 R.sub.3 SiO-- (wherein R.sub.1, R.sub.2 and R.sub.3 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.
