Electrophotographic photoreceptor, process cartridge, and image-forming apparatus

An electrophotographic photoreceptor comprising:

• a conductive substrate;
• and
• a photosensitive layer disposed on the conductive substrate,
• wherein an outermost surface layer of the electrophotographic photoreceptor contains fluorine-containing resin particles and a fluorine-containing graft polymer having a structural unit represented by general formula (FA), a structural unit represented by general formula (FB), and a structural unit represented by general formula (FC):
• where RF1, RF2, RF3, and RF4 each independently represent a hydrogen atom or an alkyl group;
• XF1 represents an alkylene chain, a halogen-substituted alkylene chain, —S—, —O—, —NH—, or a single bond;
• YF1 represents an alkylene chain, a halogen-substituted alkylene chain, —(CfxH2fx-1(OH))—, or a single bond;
• QF1 represents —O— or —NH—;
• fl, fm, and fn each independently represent an integer of 1 or more;
• fp, fq, fr, and fs each independently represent an integer of 0 or 1 or more;
• ft represents an integer of 1 or more and 7 or less;
• fx represents an integer of 1 or more;
• RF5 and RF6 each independently represent a hydrogen atom or an alkyl group;
• and fz represents an integer of 1 or more,
• wherein a number of carboxyl groups in the fluorine-containing resin particles is 0 or more and 30 or less per 106 carbon atoms, and an amount of a basic compound in the fluorine-containing resin particles is 0 ppm or more and 3 ppm or less, and
• wherein a molecular-weight distribution Mw/Mn (weight-average molecular weight Mw/number-average molecular weight Mn) of the fluorine-containing graft polymer is 1.5 or more and 5.0 or less.
