Developer carrying member, and developing apparatus using same

A developer carrying member comprising a substrate and a resin layer formed thereon,

• wherein the resin layer is obtained by thermally curing a coating material composition including the following (A) to (E):
• (A) a thermosetting resin as a binder resin
• (B) an alcohol having 1 to 4 carbon atoms as a solvent,
• (C) a resin having a unit represented by the following formula (1)
• (D) a graphitized carbon black having a graphite (002) lattice spacing of 0.3370 nm or more and 0.3450 nm or less as measured by X-ray diffraction
• (E) an acidic carbon black having a pH of 5.0 or less
• Wherein, in the formula (1),
• R1 represents a hydrogen atom or a methyl group;
• R2 represents an alkylene group having 1 to 4 carbon atoms;
• one or two or more groups selected from the group consisting of R3, R4 and R5 each represents an alkyl group having 4 to 18 carbon atoms, and each of the rest represents an alkyl group having 1 to 3 carbon atoms;
• X represents —COO—, —CONH— or —C6H4—;
• and
• A− represents an anion.
