Title:
LAMINATED ELECTROPHOTOGRAPHIC PHOTORECEPTOR, MANUFACTURING METHOD OF LAMINATED ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2017049306
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a laminated electrophotographic photoreceptor that can achieve both electrical characteristics and wear resistance.SOLUTION: A laminated electrophotographic photoreceptor comprises a photosensitive layer. The photosensitive layer includes a charge generating layer and a charge transport layer. The charge generating layer includes a charge generating agent. The charge transport layer includes a hole transport agent and a binder resin. The charge generating agent includes titanyl phthalocyanine having a main peak at the Bragg angle of 2θ±0.2°=27.2° in a CuKα characteristic X-ray diffraction spectrum. The hole transport agent includes a triarylamine derivative represented by the general formula (1). In the charge transport layer, the ratio of the mass of the hole transport agent is 0.30 or more and 0.55 or less based on the mass of the binder resin.SELECTED DRAWING: Figure 1
