摘要： PROBLEM TO BE SOLVED: To ensure high sensitivity and to suppress the rise of residual potential by incorporating a specified stilbene compd. into a photosensitive layer. SOLUTION: This photoreceptor contains a stilbene compd. represented by formula I in the photosensitive layer. In the formula I, at least one of Ar and Ar is a group represented by formula II, etc., the other is alkyl, etc., Ar is arylene, etc., when Ar is not a group represented by the formula II, etc., Ar and Ar may bond to each other optionally through a bonding group, when Ar is not a group represented by the formula II, etc., Ar and Ar may bond to each other optionally through a bonding group, and R and R or R and R may bond to each other optionally through a bonding group. Each of R -R is H, etc., R is aryl, etc., (n) is 0 or an integer of 1-5, in the case of n>=2, R 's may be different from each other and R 's may be different from each other. In the formula II, A is a benzene ring and has a condensed ring contg. a divalent residue Z forming a cyclic structure and each of R and R is H, etc.
