Abstract:
1. A contact shock dampening and development nip forming apparatus for use in an electrophotographic image forming device having a developer, a photosensitive body to form electrostatic latent images on a surface thereof, and a developing agent transfer body rotating in contact with the photosensitive body to attach a developing agent onto the electrostatic latent images formed on the photosensitive body to form visual images, comprising: a dampening/forming unit to dampen a contact shock to the photosensitive body from the developing agent transfer body and form a development nip, installed on both ends of the photosensitive body and the developing agent transfer body and disposed between the photosensitive body and the developing agent transfer body, a portion of a circumferential surface thereof having an outer diameter larger than an outer diameter of the photosensitive body and the developing agent transfer body, a difference between the outer diameters being the same as a thickness of the development nip to thereby dampen contact shocks and form the development nip.
