Abstract
An electrophotographic photosensitive member is disclosed in which a photosensitive layer and a protective layer are formed on a conductive substrate in that order. In this photosensitive member, when its surface is charged to −700 V under a 23° C./5% RH environment and irradiated with white light in a light quantity of 10 lux·sec, if the surface potential at the time 0.2 seconds have passed from the irradiation and the surface potential at the time 0.5 seconds have passed from the irradiation are defined as Vsl(0.2) and Vsl(0.5), respectively, the absolute value of Vsl(0.2) and the absolute value of Vsl(0.2)−Vsl(0.5) satisfy specific conditions.
