Title:
電子写真感光体、プロセスカートリッジ、及び画像形成装置
Document Type and Number:
Japanese Patent JP7287108
Kind Code:
B2
Abstract:
To provide an electrophotographic photoreceptor that can form an image with excellent dot reproducibility even when the intensity of exposure is low, and can prevent the generation of transfer blur.SOLUTION: An electrophotographic photoreceptor 1 comprises: a conductive substrate 2; and a photosensitive layer 3. The photosensitive layer is a single layer. The photosensitive layer contains a charge generating agent, a hole transport agent, an electron transport agent, and a binder resin. The hole transport agent is at least one compound of compounds represented by the general formula. The electron transport agent is at least one compound of compounds represented by the general formula. When the hole transport agent is a compound represented by the general formula, the electron transport agent is a compound represented by the general formula. The photosensitive layer has a thickness of 27 μm or less. A predetermined potential is 0 V or more and +450 V or less.SELECTED DRAWING: Figure 1
