    摘要： An image forming apparatus includes an image bearing member, a developer carrying member for carrying thereon a developer to transport the developer to a developing zone, and a regulation member provided in touch with the surface of the developer carrying member to regulate coat weight of the developer carried thereon. The image bearing member includes a conductive substrate and a photosensitive layer formed thereon, and the photosensitive layer contains at least one polycarbonate resin (I) having a viscosity-average molecular weight not more than 1.5×104 and at least one polycarbonate resin (II) having a viscosity-average molecular weight more than 1.5×104, the polycarbonate resin (I) being contained in a proportion of from 30% by weight to 95% by weight based on the total weight of the polycarbonate resins (I) and (II). On the developer carrying member, the developer is in a coat weight not more than 1.5 mg/cm2 at the developing zone after its regulation by the regulation member. This apparatus can prevent smeared images and enables stable and high-grade image formation.
