Abstract
PURPOSE: To prevent deterioration of an electrostatic latent image, by rendering the distance between a latent image-bearing drum and a sleeve variable at any time.
CONSTITUTION: Sleeve 1 is fixed, and magnetic roller 2 arranged in its inside rotates. When magnetic roller 2 rotates in direction arrow A, magnetic toner 3 on sleeve 1 moves in direction arrow B. Toner 3 is trimmmed to a constant thickness with doctor blade 4. When toner 3 approaches static latent image 6 on latent image bearing drum 5, a charge opposite to image 6 in polarity is injected to toner 3 to develop image 6. The distance between drum 5 and sleeve 1 is formed in a variable structure by adjstment of eccentric cam 9, accordingly permitting deterioration of image 6 to be prevented and recording density and image quality to be enhanced.
