Patent ID: 7781134

Claim:
A photoreceptor comprising: an electroconductive substrate; and a photosensitive layer located overlying the electroconductive substrate, wherein an outermost layer of the photoreceptor comprises a binder resin, wherein the binder resin comprises a polycarbonate resin and a crystalline polyester resin, wherein the crystalline polyester resin consists of units having the following formula (I): [—O—CO—(CR 1 ═CR 2 ) m —CO—O—(CH 2 ) n —] p (I) wherein each of R1 and R2 independently represents a hydrogen atom or a hydrocarbon group; and each of m, n and p is an integer; wherein the outermost layer is prepared by a method comprising: dissolving the binder resin in a solvent at a concentration of C % by weight; coating a coating liquid comprising the binder resin solution; and drying the coated liquid, wherein the binder resin solution satisfies the following relationship (1): 2≦( T 0 −T 400 )/ C (1) wherein T 0 represents a initial transmittance(%) at 400 nm of the binder resin solution; T 400 represents a transmittance(%) at 400 nm of the binder resin solution which has been allowed to settle for 400 hours under conditions of 23° C. and 40%RH; and C represents the concentration of the binder resin solution; and wherein the polycarbonate resin solution satisfies the following relationship (2): 2≦( T 0 −T 400 )/ C≦ 3 (2).
