Patent ID: 8481238

Claim:
An electrophotographic photoreceptor comprising a conductive substrate and a photosensitive layer formed thereover, wherein the photosensitive layer contains at least a polyarylate resin having a repeating structure represented by formula [1] and a compound represented by formula [6]: wherein in formula [1], Ar 1 to Ar 4 each independently represent an arylene group which may have a substituent; X is a single bond, an oxygen atom, a sulfur atom, a group represented by formula [2], or a group represented by formula [3]; R 1 and R 2 in formula [2] each independently represent a hydrogen atom, an alkyl group, or an aryl group, and R 1 and R 2 may be bonded to each other to form a ring; R 3 in formula [3] represents an alkylene group, an arylene group, or a group represented by formula [4]; R 4 and R 5 in formula [4] each independently represent an alkylene group; and Ar 5 represents an arylene group; k represents an integer of 1; and Y is a single bond, an oxygen atom, a sulfur atom, or a group represented by formula [5], wherein R 6 and R 7 each independently represent a hydrogen atom, an alkyl group, an alkoxy group, or an aryl group, and R 6 and R 7 may be bonded to each other to form a ring: wherein in formula [6], Ar 6 to Ar 9 may be the same or different and each represent an aryl group which may have a substituent.
