摘要：
A process cartridge detachably mountable on the main body of an electrophotographic apparatus, integrally supports a photosensitive drum for bearing toner images, and an intermediate transferring belt having a contact part with the photosensitive drum. The moisture amount of the intermediate transferring belt at 23° C./50% RH is less than 1% by weight and the sum of the surface roughness Ra of the photosensitive drum and the surface roughness Ra of the intermediate transferring belt is less than 0.8 &mgr;m. The present invention also provides an electrophotographic apparatus having the process cartridge and an image forming method using the electrophotographic apparatus.
