Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2022069077
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that is excellent in electrification stability and prevention of transfer memory.SOLUTION: An electrophotographic photoreceptor 1 comprises a conductive substrate 2 and a photosensitive layer 3. The photosensitive layer is a single layer and contains a charge generating agent, a hole transport agent, a first electron transport agent, a second electron transport agent, and polyarylate resin. The polyarylate resin includes repeating units represented by specific formulas (1), (2), and (3), and the ratio n1/n2 of the number n1 of the repeating unit (1) to the number n2 of the repeating unit (2) is 1.0 or more. The first electron transport agent includes a compound represented by the formula (A15) or (A16), and further includes a second electron transport agent represented by a specific formula.SELECTED DRAWING: Figure 1
