Classification: CPC G | IPC G

Claim 10:
11. An image forming apparatus comprising:
an electrophotographic photoreceptor including a photosensitive layer;
a charging unit that charges a surface of the electrophotographic photoreceptor;
an electrostatic-image-forming unit that forms, on the charged surface of the electrophotographic photoreceptor, an electrostatic image;
a development unit that houses an electrostatic image developer including an electrostatic-image-developing toner, and uses the electrostatic image developer to develop the electrostatic image formed on the surface of the electrophotographic photoreceptor to form a toner image;
an intermediate transfer body having a surface to which the toner image is transferred;
a first transfer unit that subjects the toner image formed on the surface of the electrophotographic photoreceptor to first transfer onto the surface of the intermediate transfer body;
a second transfer unit that subjects the toner image transferred onto the surface of the intermediate transfer body to second transfer onto a surface of a recording medium;
a cleaning unit including a cleaning member that is in contact with the surface of the electrophotographic photoreceptor and cleans the surface of the electrophotographic photoreceptor; and
a lubricant supply unit that houses a lubricant solid containing, in a content of 92 mass % or more and 100 mass % or less, a lubricant having a polygonal network bond structure and that supplies the lubricant having the polygonal network bond structure to a position where the cleaning member is in contact with the electrophotographic photoreceptor,
wherein the lubricant solid has a Martens hardness at 23° C. of 24 N/mm2 or more and 80 N/mm2 or less.
