    摘要： A process cartridge which is detachably mountable to a main body of an electrophotographic apparatus, includes an electrophotographic photosensitive member to carry a toner image; an intermediate transfer belt having a contact part with the photosensitive member, and a primary transfer unit to primarily transfer the toner image at the contact part from the photosensitive member to the intermediate transfer belt, being integrally supported in one body. After the contact part is formed by the photosensitive member and the intermediate transfer belt is brought into contact with under a linear pressure of 0.5 N/cm and is left for 10 hours in an environment of 45° C./95% RH, differences in the dark portion potential and the light portion potential of the photosensitive member between the contact part and the non-contact part of the photosensitive member are respectively less than 20%, and no crack having a length of not less than 1 mm occurs in any of the surfaces of the photosensitive member and the intermediate transfer belt. An electrophotographic apparatus having the process cartridge is also disclosed.
