Abstract

PURPOSE: To form the good quality images of high density at a high speed by using a developer supply member which performs squeezing-out and absorbing of the developer along with elastic deformation.
CONSTITUTION: An elastic foam 3 composed of foamed polyurethane is disposed around a central roller 2 composed of a rigid material such as metal or rigid synthetic resin or the like and is covered with a full covering 4 to form a developing roller 1, which is then pressure-contacted to the electrostatic latent image carrying surface of a photosensitive drum. Then, the elastic foam 3 of the developing roller 1 sucks the developer from a developing vessel while making elastic deformation, and squeezes the developer out onto the electrostatic latent image carrying surface and further squeezes off the excess developer, thereby developing the electrostatic latent image satisfactorily at a high speed. Disposition of the developing roller 1 in proximity to the photosensitive drum after providing developing electrode effect thereto causes more effective development to be performed
