Electrophotographic photoreceptor comprising a photosensitive layer containing a naphthylhydrazone compound

摘要

An electrophotographic photoreceptor is formed by a photosensitive layer containing a naphtylhydrazone compound of the formula: (* CHEMICAL STRUCTURE *) wherein X and Y are independently a hydrogen atom, lower alkyl group, lower alkoxy group, phenoxy group or arylalkoxy group; R1 is a naphtyl group; R2 is a hydrogen atom, lower alkyl group, allyl group, substituted or unsubstituted phenyl group, or aralkyl group; and l and m are 1 or 2. The photoreceptor thus formed is not only highly sensitive but resistant to ozone deterioration, which markedly improves the durability thereof.
