Electrophotographic photoreceptor, image-forming device, and process cartridge

An image-forming device, comprising:

• an electrophotographic photoreceptor comprising a conductive support and, on the conductive support, at least a photosensitive layer, the electrophotographic photoreceptor comprising a surface layer that may be the same as or different from the photosensitive layer and that includes fluororesin particles and a fluorinated alkyl group-containing copolymer containing a repeating unit represented by the following Structural Formula A, the content of quaternary ammonium salt in the surface layer being about 50 ppm or less;
• a charging unit that charges a surface of the electrophotographic photoreceptor;
• an electrostatic latent image-forming unit that forms an electrostatic latent image on the charged surface of the electrophotographic photoreceptor;
• an image-forming unit that forms a toner image by developing the electrostatic latent image formed on the surface of the electrophotographic photoreceptor using a developer;
• and
• a transfer unit that transfers the toner image formed on the surface of the electrophotographic photoreceptor to a surface of a transfer-receiving material:
• wherein, in Structural Formula A, l represents a positive number of 1 or more;
• p represents 0 or a positive number of 1 or more;
• t represents a positive number of from 1 to 7;
• R1 represents a hydrogen atom or an alkyl group;
• and Q represents —O— or —NH—.

A process cartridge comprising, integrally:

• an electrophotographic photoreceptor comprising a conductive support and, on the conductive support, at least a photosensitive layer, the electrophotographic photoreceptor comprising a surface layer that may be the same as or different from the photosensitive layer and that includes fluororesin particles and a fluorinated alkyl group-containing copolymer containing a repeating unit represented by the following Structural Formula A, the content of quaternary ammonium salt in the surface layer being about 50 ppm or less;
• and
• at least one of a charging unit that charges a surface of the electrophotographic photoreceptor, an electrostatic latent image-forming unit that forms an electrostatic latent image on the charged surface of the electrophotographic photoreceptor, an image-forming unit that forms a toner image by developing the electrostatic latent image formed on the surface of the electrophotographic photoreceptor using a developer, a transfer unit that transfers the toner image formed on the surface of the electrophotographic photoreceptor to a surface of a transfer-receiving material, or a cleaning unit that removes a residual toner on the surface of the electrophotographic photoreceptor after the transfer,
• the process cartridge being attachable to and detachable from a main body of an image-forming device:
• wherein, in Structural Formula A, l represents a positive number of 1 or more;
• p represents 0 or a positive number of 1 or more;
• t represents a positive number of from 1 to 7;
• R1 represents a hydrogen atom or an alkyl group;
• and Q represents —O— or —NH—.
