ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND IMAGE FORMING APPARATUS PROVIDED WITH THE SAME |
摘要 |
The present invention provides an electrophotographic photoreceptor comprising a multilayered photosensitive layer or a monolayer photosensitive layer,;wherein the multilayered photosensitive layer comprises at least a charge generation layer containing a charge generation material and a charge transport layer containing a charge transport material that are stacked on a conductive substrate in this order, and
the monolayer photosensitive layer contains a charge generation material and a charge transport material that is stacked on a conductive substrate,
wherein the electrophotographic photoreceptor contains 5 to 17 wt % of fluorine resin fine particles and their aggregates with respect to all photoreceptor components in a surface layer of the photoreceptor,
wherein the fluorine resin fine particles are 0.1 to 0.5 μm in average primary particle diameter,
the aggregates are 1 to 3 μm in constant direction tangent diameter,
the number of the aggregates is 10 to 40% of the number of the fluorine resin fine particles. |
