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 JP6677212
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that prevents the occurrence of white spots in a formed image.SOLUTION: An electrophotographic photoreceptor contains a monolayer of photosensitive layer, a charge generator, an electronic transportation agent, and a binder resin. The electronic transportation agent contains a specific compound having a halogen atom. The binder resin contains a polyarylate resin containing general formula (11), general formula (12), and a terminal group represented by (13). In general formula (13), Ris an open-chain aliphatic group having at least one fluoro group. The amount of charge of calcium carbonate when the photosensitive layer and the calcium carbonate are rubbed with each other is +8.0 μC/g or more.SELECTED DRAWING: None
