Abstract
PURPOSE: To form developed images of good quality with good efficiency through the use of a one-component type developer and efficiently transfer these with high accuracy in a short time following to this by covering the surface of a developer feed means with an inorganic semiconductor layer.
CONSTITUTION: After a photosensitive drum 1 is evenly charged with a corona charger 2, it is exposed to imagewise patterns in an optical means part 3, whereby electrostatic latent images are formed. Next, in a developing device part 4, a toner 5 which contains organic semiconductor and magnetic material and is normally of insulation type is held onto a sleeve form toner feed member 7 which is built in with a permanent magnet 7a and has a covering 7b of inorganic semiconductor in the surface, while its volume is being defined by a doctor blade 8 and is injected with the charges of a polarity opposite from that of the latent images by the action of the electric field produced between the latent images and member 7 at the position in the proximity of latent image on the drum 1, whereby the latent image are developed. Next, in a transfer part 9, the toner images are transferred by a corona charger 11 onto the plain paper 10 having been delivered out from a paper feed part 6.
