To ensure superior wear resistance at the time or repetitive use and to suppress the occurrence of an abnormal image during repetitive use by forming a protective layer contg. a specified high molecular electric charge transferring material.
A photosensitive layer 2 and a protective layer 3 contg. a high molecular electric charge transferring material represented by the formula are successively formed on an electrically conductive substrate 1. In the formula, each of R'1-R'3 is optionally substd. alkyl or halogen, R'4 is H or optionally substd. alkyl, each of R1 and R2 is optionally substd. aryl, each of (o), (p) and (q) is an integer of 0-4, the ratio of k:j is (0.1-1):(0-0.9), (n) is an integer of 5-5,000 as the number of repeating units and X is a divalent aliphatic group, a divalent alicyclic group, etc.
