Electrophotographic photosensitive member and image forming apparatus

An electrophotographic photosensitive member comprising:

• a conductive substrate;
• and
• a photosensitive layer disposed directly or indirectly on the conductive substrate, wherein
• the photosensitive layer has a charge generating layer and a charge transport layer disposed in order from the conductive substrate,
• the charge generating layer contains a charge generating material,
• the charge transport layer contains a charge transport material, a binder resin, and a pigment that absorbs light having an irradiation wavelength,
• the binder resin includes a polyarylate resin including a repeating unit represented by general formula (1) shown below, and
• the pigment is a naphthalocyanine compound represented by general formula (2) or general formula (3) shown below,
• where in general formula (1),
• v and w each represent, independently of one another, 2 or 3,
• r, s, t, and u each represent, independently of one another, a number greater than or equal to 0,
• r+s+t+u=100,
• r+t=s+u,
• r/(r+t) is at least 0.00 and no greater than 0.90,
• s/(s+u) is at least 0.00 and no greater than 0.90, and
• X and Y each represent, independently of one another, a divalent group represented by chemical formula (1-1), chemical formula (1-2), chemical formula (1-3), or chemical formula (1-4) shown below,
• in general formula (2),
• R1, R2, R3, R4, R5, and R6 each represent, independently of one another, a hydrogen atom, an alkyl group optionally having a substituent and having a carbon number of at least 1 and no greater than 6, an aryl group optionally having a substituent and having a carbon number of at least 6 and no greater than 14, an alkoxy group optionally having a substituent and having a carbon number of at least 1 and no greater than 6, a phenoxy group optionally having a substituent, a thioalkyl group optionally having a substituent and having a carbon number of at least 1 and no greater than 6, or a thiophenyl group optionally having a substituent, with the proviso that R1, R2, R3, R4, R5, and R6 do not all simultaneously represent hydrogen atoms, and
• M represents a metal atom optionally having a ligand, and
• in general formula (3),
• R7, R8, R9, R10, R11, and R12 each represent, independently of one another, a hydrogen atom, an alkyl group optionally having a substituent and having a carbon number of at least 1 and no greater than 6, an aryl group optionally having a substituent and having a carbon number of at least 6 and no greater than 14, an alkoxy group optionally having a substituent and having a carbon number of at least 1 and no greater than 6, a phenoxy group optionally having a substituent, a thioalkyl group optionally having a substituent and having a carbon number of at least 1 and no greater than 6, or a thiophenyl group optionally having a substituent, with the proviso that R7, R8, R9, R10, R11, and R12 do not all simultaneously represent hydrogen atoms.
