Electrophotographic photosensitive member, process cartridge, and image forming apparatus

An electrophotographic photosensitive member comprising:

• a conductive support;
• and
• a photosensitive layer disposed on the conductive support,
• wherein a top surface layer of the electrophotographic photosensitive member includes fluorine-containing resin particles, a fluorine-containing dispersant, and two or more charge transporting materials,
• wherein, when the charge transporting materials are listed in order of decreasing HOMO energy levels, a difference in HOMO energy level between each adjacent two of the charge transporting materials is more than 0 eV and 0.2 eV or less,
• wherein a percentage ratio A of an amount of each of the charge transporting materials to a total amount of the charge transporting materials satisfies a condition 1 below,
• [(100/N)−(100/N×0.3)]%≤A≤[(100/N)+(100/N×0.3)]% Condition 1
• where, in the condition 1, N represents a number of types of the charge transporting materials included in the top surface layer, and
• wherein the charge transporting materials include a compound represented by Formula (CT1) and/or a compound represented by Formula (CT2),
• where, in Formula (CT1), RC11, RC12, RC13, RC14, RC15, and RC16 each independently represent a hydrogen atom, a halogen atom, an alkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, or an aryl group having 6 to 30 carbon atoms, and any adjacent two substituents may be bonded to each other to form a hydrocarbon ring structure;
• and n and m each independently represent 0, 1, or 2;
• where, in Formula (CT2), RC21, RC22, and RC23 each independently represent a hydrogen atom, a halogen atom, a hydroxyl group, a formyl group, an alkyl group, an alkoxy group, or an aryl group.
