Abstract
An image forming unit includes a photosensitive drum as an image holding member for converting an optical image formed via an optical system into a latent image and subsequently depositing a developing material thereon to hold the image. The apparatus also includes a developing roller as a developing portion for supplying the developing material to develop the latent image held on the photosensitive drum to the image with the developing material. The apparatus further includes a gap regulating mechanism for setting bearings, disposed on both ends of a rotation drive shaft of the photosensitive drum, for rotatably fixing the photosensitive drum to a system main body frame and bearings, disposed on both ends of the developing roller, for rotatably supporting a rotation drive shaft of the developing roller by a developing portion main body. With such a unit, a peripheral surface of the photosensitive drum always maintains a constant gap from the peripheral surface of the developing roller.
