Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR
Document Type and Number:
Japanese Patent JP2020079915
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that is excellent in sensitivity and wear resistance and can prevent LSU light reflection stripes.SOLUTION: An electrophotographic photoreceptor comprises: a conductive substrate; and a photosensitive layer directly or indirectly provided on the conductive substrate. The photosensitive layer has a charge generating layer and a charge transport layer provided sequentially from the conductive substrate. The charge transport layer contains a binder resin, a hole transport agent, and titanyl phthalocyanine. The binder resin contains a polyarylate resin having a repeating unit represented by a general formula (1) and a general formula (2), and a terminal group represented by a general formula (3). The titanyl phthalocyanine has a main peak at a Bragg angle of (2θ±0.2°) at 27.2°. A content of titanyl phthalocyanine in the charge transport layer is 0.1 parts by mass or more and 0.5 parts by mass or less based on 100 parts by mass of the binder resin.SELECTED DRAWING: None
