Method of manufacturing image bearing member, image bearing member, and image forming apparatus

A method of manufacturing an image bearing member comprising:

• forming a charge generation layer overlying an electroconductive substrate;
• forming a charge transport layer overlying the charge generation layer, the charge transport layer comprising a charge transport material having a molecular weight of from 600 to 900 and a binder resin;
• and
• forming a protection layer overlying the charge transport layer by applying a liquid application comprising a polymerizable compound having a charge transport structure, a polymerizable compound having no charge transport structure, a filler, a polycarboxylic acid compound, and cyclopentanone and curing the polymerizable compound having a charge transport structure, and the polymerizable compound having no charge transport structure,
• wherein the following relationship I is satisfied:
• 6≦(A×B/C)≦40 Relationship I
• where A represents a content in units of grams of the polycarboxylic acid compound, B represents an acid value in units of mgKOH/g of the polycarboxylic acid compound, and C represents a content in units grams of the filler.
