Document Type and Number:

WIPO Patent Application WO/2017/141677

Kind Code:

A1

Abstract:

This electrophotographic photosensitive body (1) is provided with a conductive base (2) and a photosensitive layer (3). The photosensitive layer (3) is a single layer-type photosensitive layer, and contains at least a charge generator, a hole transport agent, an electron transport agent, and a binder resin. The charge generator contains a metal-free phthalocyanine. The hole transport agent contains a triphenylamine derivative represented by general formula (1). The electron transport agent contains a quinone derivative represented by general formula (2). In general formula (1), R1, R2, R3, m1, m2, k, p and q are the same as R1, R2, R3, m1, m2, k, p and q defined in the description.
