PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that has image defects due to a ghost phenomenon suppressed under a room temperature room moisture environment, and a cold temperature low moisture environment, which is a severe condition.SOLUTION: An electrophotographic photoreceptor contains a gallium phthalocyanine crystal, in which the gallium phthalocyanine crystal contains an amide compound expressed by a following expression (1) and N, N-dimethylformamide in the crystal. R-NHCHO (1) (where in the expression (1), Rdenotes a methyl group, a propyl group, or a vinyl group.)SELECTED DRAWING: None |
