電子写真感光体
Document Type and Number:
Japanese Patent JP6763354
Kind Code:
B2
Abstract:
To provide a compound that can improve the electrical characteristics of a photoreceptor and prevent crystallization of a photosensitive layer.SOLUTION: An electrophotographic photoreceptor 1 comprises a conductive substrate 2 and a photosensitive layer 3. The photosensitive layer 3 is a single layer. The photosensitive layer 3 contains a charge generating agent, a hole transport agent, a binder resin, and an electron transport agent. The ratio of the mass of the hole transport agent to the mass of the binder resin is 0.50 or more. The hole transport agent contains a compound represented by the general formula (1).SELECTED DRAWING: Figure 1
