Summary: | In an electrophotographic photosensitive member comprising a cylindrical support, and provided thereon a photosensitive layer and a protective layer in this order, which cylindrical support has an outer diameter of less than 30 mm, the difference between a coefficient of thermal expansion alpha1 measured from the top of the protective layer and a coefficient of thermal expansion alpha2 measured after the protective layer has been removed, |alpha1 -alpha2 |, is more than 5.0x10-7>° C.-1 >to less than 1.0x10-4>° C.-1>, and the modulus of elastic deformation We % measured from the top of the protective layer is more than 30% to less than 60%. Also disclosed are a process cartridge and an electrophotographic apparatus which have such an electrophotographic photosensitive member. |
