Abstract: A color electrophotographic apparatus includes a photosensitive belt arranged obliquely, and a plurality of developing machines arranged on one side of the photosensitive belt in a stacked manner so as to be displaced from one another in a horizontal direction. The photosensitive belt is movable from below to above in a direction opposite to a direction of gravity when in a developing position. The developing machines include a non-magnetic, one component contact developing system having a developing roll for adhering toner on the photosensitive belt and a blade disposed below the developing roll for controlling an amount of toner adhering to the developing roll.

Abstract: An electrophotographic printing machine has a photoreceptive member. The photoreceptive member is charged and then exposed with a light image representation to form a latent image. An electric field, less than that required to re-charge the photoreceptive member, is applied to the latent image to increase the rate of discharge of the exposed portions of the latent image. The latent image is then developed.

Abstract: A high slope charging device including a DC portion followed by an AC portion. The high slope device includes an insulative shell housing, an electrode and a corona wire. The electrode is coupled to direct current power source which supplies a constant potential to the electrode thereby generating a corona at the electrode.

Abstract: A transfer device according to the present invention is comprised of a transfer material carrying member such as paper, a transfer charger provided in the transfer material carrying member, and an opposite member comprising elastic material opposite to the transfer member. The opposite member is movable to both a contact position with the surface of the transfer material carrying member and a separate position away from the surface of the transfer material carrying member. When the transfer material positions at the adsorption position, the opposite member is switched to move to the contact position from the separate position to carry a transfer material thereon. After the transfer material is carried, the transfer material is adsorbed on the surface of the transfer material carrying member.
