Document Type and Number:
Japanese Patent JP7298271
Kind Code:
B2
Abstract:
To provide an electrophotographic photoreceptor that is excellent in wear resistance and can prevent the occurrence of turn-up of a blade.SOLUTION: An electrophotographic photoreceptor 1 comprises: a conductive substrate 2; and a photosensitive layer 3. The photosensitive layer contains a charge generating agent, a hole transport agent, a binder resin, and fluororesin particles. The binder resin contains a polyarylate resin. The polyarylate resin includes a repeating unit represented by a specific general formula and a repeating unit represented by a specific chemical formula. The ratio of the number n1 of the repeating units represented by a specific general formula to the number n2 of the repeating units represented by a specific chemical formula, n1/n2 is 1.0 or more.SELECTED DRAWING: Figure 1
