Abstract
PURPOSE: To make it possible to intensely agitate the toner particles with a view to developing a satiafactory electric latent image stably without being influenced by temperature, moisture or the like by using a one-component magnetic developing agent having a high holding power.
CONSTITUTION: A photosensitive drum 9, in which a conductive metal drum 9" grounded to the earth is equipped on its circumference with a xerographic photosensitive element 9', is turned at a constant speed in the direction f arrow. A conductive non-magnetic metal cylinder 11' is formed on a portion of its circumference with a non-magnetic insulating layer 11", and a multi-polar magnetic roll 14 is turned at a high speed within a cylindrical sleeve 11 which is fixed irrotational. As a result, the developing agent, which is stored in a container 12 and which is made of a magnetic toner having a magnetic holding power higher than 170 Oe, is carried out along the circumference of the sleeve 11 so that the quantity of the developing agent is regulated by the blade 13 which is made of an insulating material. At the developing unit, the developing agent is frictionally charge by the disturbances so that the electric latent image on the drum 9 is developed.
