Abstract

Provided is a fluorine-containing resin particle dispersion including: fluorine-containing resin particles, a resin which is not dissolved in at least one solvent in a group of hydroxyl group-containing solvents including an alcohol-based solvent having 1 to 10 carbon atoms, containing no aromatic ring in the molecule structure, and a water-based medium, and which is adhered on the surface of the fluorine-containing resin particles, and at least one solvent, in which the resin is not dissolved, in the group of hydroxyl group-containing solvents, in which the fluorine-containing resin particles having the resin adhered on the surface thereof are dispersed.

First claim

What is claimed is:

1. An electrophotographic photoreceptor comprising:
a substrate, and
a surface photosensitive layer which contains fluorine-containing resin particles and a resin adhered on the surface of the fluorine-containing resin particles,
wherein the resin is not dissolved in at least one solvent selected from the group consisting of a water-based solvent and an alcohol-based solvent having 1 to 10 carbon atoms,
wherein the alcohol-based solvent contains no aromatic ring in the molecule structure.

2. The electrophotographic photoreceptor according to claim 1 ,
wherein the resin is a random or block copolymer of an acrylate having a perfluoroalkyl group and a monomer having no fluorine.

3. An image forming apparatus comprising:
the electrophotographic photoreceptor according to claim 1 ,
a charging device that charges the electrophotographic photoreceptor,
an exposure device that exposes the surface of the charged electrophotographic photoreceptor to form an electrostatic latent image on the surface,
a developing device that develops the electrostatic latent image with a developer to form a toner image, and
a transfer device that transfers the toner image to a recording medium.

4. A process cartridge,
comprising the electrophotographic photoreceptor according to claim 1 ,
wherein the process cartridge is configured to be detachable from an image forming apparatus.
