Abstract
PURPOSE: To make a plurality of copies from one electrostatic latent image, by closely contacting a toner layer on a toner supplying member with an image bearing member with an electrostatic image latent formed, and developing said image without leakage.
CONSTITUTION: Photosensitive drum 1 rotates anticlockwise, developing roller 14 rotates clockwise as fast as drum 1 in peripheral velocity. Roller 14 and drum 1 are contacted closely, but especially high pressure in not applied. Roller 14 having toner layer 20 formed with scooping roller 13 allows layer 20 to contact drum 1 without causing mechanical friction between roller 14 and the circumference of drum 1, thus permitting an electrostatic latent image to be developed without leakage, and therefore, a plurality of copies free from difference in image quality to be made from the same electrostatic latent image by preventing its leakage.
