POSITIVELY CHARGEABLE SINGLE-LAYER ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS

摘要

A positively chargeable single-layer electrophotographic photosensitive member is used as an image bearing member in an image forming apparatus including a charging section configured to be in contact with the image bearing member to apply a voltage thereto. The positively chargeable single-layer electrophotographic photosensitive member includes a conductive substrate and a photosensitive layer. The photosensitive layer contains at least a charge generating material, a hole transport material, an electron transport material, and a binder resin. The hole transport material contains a triarylamine derivative represented by the following general formula (I). In general formula (I), R1, R2, m and n have the same meaning as R1, R2, m, and n defined in the description.;

1. A positively chargeable single-layer electrophotographic photosensitive member used as an image bearing member in an image forming apparatus including a charging section configured to be in contact with the image bearing member to apply a voltage thereto, comprising:
a conductive substrate; and a photosensitive layer, wherein the photosensitive layer contains at least a charge generating material, a hole transport material, an electron transport material, and a binder resin, and the hole transport material contains a triarylamine derivative represented by the following general formula (I): wherein R1 and R2 each independently represent a halogen atom, an optionally substituted alkyl group having a carbon number of at least 1 and no greater than 6, an optionally substituted alkoxy group having a carbon number of at least 1 and no greater than 6, or an optionally substituted aryl group having a carbon number of at least 6 and no greater than 14, m and n each independently represent an integer of 0 or more and 4 or less, if m represents an integer of 2 or more, a plurality of R1s present on the same aromatic ring may be the same as or different from one another, and if n represents an integer of 2 or more, a plurality of R2s present on the same aromatic ring may be the same as or different from one another.
