Patent ID: 8275290

Claim:
An electrophotographic photosensitive body comprising a substrate and a photosensitive layer formed on the substrate, wherein, when a reflectance to an exposure light for forming an electrostatic latent image is defined as a first reflectance, and a reflectance to a eliminating light for eliminating charges constituting the electrostatic latent image is defined as a second reflectance, the first reflectance is positively correlated with a light intensity rate of the exposure light, and the second reflectance is positively correlated with the light intensity rate in a first case in which a ratio of an amount of change of the first reflectance to an amount of change of the light intensity rate is less than 1, while it is negatively correlated with the light intensity rate in a second case in which a ratio of an amount of change of the first reflectance to an amount of change of the light intensity rate is more than 1.
