Abstract:
The invention relates to an electrophotographic photoreceptor which is excellent in abrasion resistance and electrical properties by using a fluororesin and a polymer containing a structure represented by a specific formula, and has a long life span, an electrophotographic photoreceptor cartridge and an image forming apparatus including the electrophotographic photoreceptor, and a dispersant which is excellent in dispersibility of a fluororesin particle, and the electrical properties, and the compatibility with a binder resin.

Claim (Index 5):
The electrophotographic photoreceptor according to  claim 1 ,\n wherein R 3  in the structure represented by Formula (1) has a structure represented by Formula (6): wherein in the Formula (6), R 17  to R 24  each independently represents a hydrogen atom, an alkyl group having 1 to 20 carbon atoms which may have a substituent, an alkoxy group, and an aromatic group or a halogen group which may be substituted; X 2  represents a single bond, \u2014CR 25 R 26 \u2014, an oxygen atom, CO or a sulfur atom; R 25  and R 26  each independently represents a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, an aromatic group having 6 to 12 carbon atoms, or R 25  and R 26  represent a cycloalkylidene group having 5 to 10 carbon atoms which may have a substituent, and is formed by combining R 25  and R 26 ; Ar 1  and Ar 2  each independently represents an amylene group or a cyclohexylene group which may have a substituent; Y represents a single bond, an oxygen atom, or a sulfur atom; and k represents an integer of 0 to 1.
