摘要 |
PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which has high durability, suppresses image degradation due to rise of residual potential or image blurring, and stably obtains images of high image quality even in long-term repetitive use. SOLUTION: In the electrophotographic photoreceptor, a layer remotest from a conductive support contains at least one organic compound having an acid number of 10-700 (mgKOH/g) and at least one selected from the compounds represented by formula (1), wherein R<SP>1</SP>and R<SP>2</SP>each represent a substituted or unsubstituted alkyl or aromatic hydrocarbon group and may be the same or different, but one of R<SP>1</SP>and R<SP>2</SP>is a substituted or unsubstituted aromatic hydrocarbon group, and R<SP>1</SP>and R<SP>2</SP>may bond to each other to form an N-containing substituted or unsubstituted heterocyclic group; and Ar represents a substituted or unsubstituted aromatic hydrocarbon group.
