Abstract
PURPOSE: To make it possible to obtain an image, which always has stable density, while enlarging the allowability of contacting conditions, and to use the developing apparatus also as a cleaning device by connecting preset tension generating means to a developing member.
CONSTITUTION: A photosensitive drum 5 and a developing roller 6 are turned together so that a powder developing agent 7 in a developing agent container 8 is trapped in accordance with the charges of an electrostatic latent image formed on the drum 5 thereby to visualize an electrostatic latent image. By the tension of a coil spring 10 which has its both ends held by a supporting member 11 so as to provide tension generating means attached to the shaft 9 of the roller 6, the roller 6 is forced into contact with the drum 5, while interposing a developing agent layer 20 inbetween, to apply a preset contact pressure. Since, moreover, a doctor 13 is biased by a compression spring 12, the thickness of the layer 20 can be maintained at a constant.
