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 JP7380044
Kind Code:
B2
Abstract:
To provide an electrophotographic photoreceptor that has high surface smoothness regardless of the type of fluorine-containing resin particles.SOLUTION: An electrophotographic photoreceptor has a conductive substrate and a photosensitive layer provided on the conductive substrate. An outermost surface layer includes fluorine-containing resin particles and a fluorine-based graft polymer having a fluorinated alkyl group. A molecular weight distribution curve of the fluorine-based graft polymer has two or more peaks. In the molecular weight distribution curve of the fluorine-based graft polymer, when the peak area of a peak P1 at which the molecular weight is minimum is S1 and the peak area of a peak P2 at which the molecular weight is maximum is S2, the relationship of S1≤S2 is satisfied.SELECTED DRAWING: None
