Abstract: In a developing device for visualizing an electrostatic latent image using two-component developer containing toner and magnetic carrier, excellent development will be performed and deterioration of the developer will be prevented. A developer carrier opposite to an image carrier having an electrostatic latent image formed thereon is prepared by forming a thin layer of aluminum with a thickness of 3 .mu.m or less on the peripheral surface of a roll-shaped member made of ferrite, and the surface roughness Rz of the peripheral surface of the foregoing ferrite roll is set to 50 .mu.m or less. N-poles and S-poles are alternately magnetized at a 50-to-250-.mu.m pitch along the peripheral surface of this ferrite roll. These magnetic poles can be magnetized to have uniform intensity because the peripheral surface of the roll has been smoothly finished, and a developer layer having only substantially one layer of the carrier uniformly attracted is formed on the peripheral surface.

Abstract: An image forming apparatus and an image forming method in which a latent image is formed by scanning the surface of an image bearing body with a laser light blinking in accordance with pulse-width modulation based on an image signal. Output-control-wave generating device generates an output control wave having a peak for a write time of each picture element. The output control wave is turned on and off by a gate circuit with timing determined by an exposure control signal generated by exposure control device. A signal output by the gate circuit is converted by a V/I converter into a driving current wave for controlling radiation of a laser light by an exposure unit. In this way, exposure energy produced by the exposure unit can be concentrated on an exposure time duration of each picture element, allowing the amount of mutual interference among picture elements to be reduced.

Abstract: In a color image forming apparatus, a screen of each of electrostatic latent images to be formed by an exposing device has a parallel lines structure, and phases of the electrostatic latent images each having the parallel lines structure for at least two different colors are made different from each other. Accordingly, the color image forming apparatus can totally solve the problem caused by the rise in potential of exposed portions by toner charges and the dielectric property of toner layers and the problem caused by the toner shielding effect to thereby allow faithful reproduction of a highlight area important for a good halftone image, especially a high-quality color image.
