ABSTRACT:
An electrophotographic organic photosensitive layer is formed by using a diphenoquinone derivative A and a diphenoquinone derivative B having a larger absolute value for reduction potential as electron transport materials. The diphenoquinone derivative A is, for example, 3,5-dimethyl-3',5'-di-t-butyl-4,4'-diphenoquinone. The diphenoquinone derivative B is, for example, 3,3',5,5'-tetra-t-butyl-4,4'-diphenoquinone. The diphenoquinone derivative B is included in the proportion of 3 to 50 wt % on the basis of the total weight of the electron transport materials (the diphenoquinone derivatives A and B).
