摘要：
The present invention provides a latent electrostatic image bearing member which includes a support, a charge generating layer, and a charge transporting layer, the charge generating layer and the charge transporting layer being arranged in this order on or above the support, wherein the charge transporting layer comprises at least a charge transporting material and a binder resin and has a thickness of 30 μm to 50 μm; and the distribution representing the relation between the absorbance ratio of the charge transporting material and the binder resin measured by infrared spectroscopy and the distance from the surface of the charge transporting layer toward the thickness direction thereof represents a generally linear shape without having inflection points within 20 μm from the surface of the charge transporting layer toward the thickness thereof.
