PROBLEM TO BE SOLVED: To improve the surface slidability of the photoreceptor without adversely affecting electric characteristics and printing resistance by incorporating a polycarbonate resin having polysiloxane on one or both of the ends and a specified molecular weight in a photosensitive layer. SOLUTION: The photosensitive layer contains at least one of binder resins the polycarbonate resin having the repeating structural units represented by formula I and the polysiloxane units on one or both of the ends, represented by formula II, and the polysiloxane parts freed from W and R13 amount to the total weight of all the binder resin in 0.01-5 weight %. In formulae I and II, each of Y1-Y8 is an H atom or a 1-10 C saturated aliphatic hydrocarbon group or the like; X is a -O- or -S- atom or an aromatic ring or the like; R13 is an aliphatic or aromatic divalent organic group; W is a single bond or an O atom or the like; and each of R8-R12 is a 1-10C saturated hydrocarbon group or the like.
