Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2021110804
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that has high wear resistance.SOLUTION: An electrophotographic photoreceptor has a conductive substrate, and a single layer-type photosensitive layer that is provided on the conductive substrate, the photosensitive layer including a polycarbonate resin, a charge generating material, a hole transport material having a triarylamine structure, and an electron transport material. When the peak intensity (P2F) of a fingerprint region (695 cm-1) unique to the hole transport material to the peak intensity (1775 cm-1)(P1F) derived from a carbonyl group of the polycarbonate resin in a surface of the photosensitive layer is (PF), and the peak intensity (P2B) of a fingerprint region (695 cm-1) unique to the hole transport material to the peak intensity (1775 cm-1)(P1B) derived from a carbonyl group of the polycarbonate resin on a surface of the photosensitive layer facing the conductive substrate is (PB), which are measured by an infrared spectrophotometer (IR), the (PF) and (PB) satisfy the relationship of 0.2≤(PF)/(PB)≤0.37.SELECTED DRAWING: Figure 1
