摘要:
In an image processing apparatus that includes an order placement means for executing an operation associated with order placement of an expendable used in an image forming apparatus, data associated with image formation is accumulated to have a timing associated with order placement as a trigger, and the operation of the order placement means is controlled on the basis of the accumulated value. In this manner, redundant orders for expendables can be prevented.

There is provided an image forming apparatus such as a latent image forming apparatus, in which the density of a half tone is stable independent on a write position of a main scanning line, even if a plurality of semiconductor lasers are used. The image forming apparatus has a latent image forming unit for pulse-width-modulating a drive signal of the semiconductor laser in response to the write position of image data. The latent image forming unit has an image sorting circuit for sorting the image data into an odd line and an even line, a memory for storing a turning on position, a pulse generating position control circuit for generating a pulse generating position signal, a PWM circuit for generating a triangular wave in accordance with the pulse generating position signal, and a beam-A-circuit and a beam-B-circuit, which control beams from the semiconductor laser.

An image forming and apparatus is provided in which a halftone density of an image is stabilized irrespective of a timing at which writing on scanning lines is started, even when using multiple laser beams. First, it is determined whether or not a portion exposed by adjacent laser beams (i.e., exposed by both of two beams simultaneously) is present. If the result of the determination is affirmative, it is then determined whether or not a portion adjacent to the exposed portion and not exposed by a laser beam is present. If the result of this determination is affirmative, exposure by fine dots is added to the portion not exposed by a laser beam.

An image forming apparatus forming a preferable image without white dots caused by excessive charging when a halftone image is formed by providing a potential difference between a surface potential of a photosensitive drum immediately before charging by a charging device, and that of the drum after the charging in an image forming area of the drum. At least one of a charging bias and a transfer bias is changed between a first area and a second area. The first area is an area on the drum that passes a transfer portion when a recording medium is not present between the roller and the drum, and on that a latent image is to be formed. The second area is an area on the drum that passes the transfer portion when the medium is present between the roller and the drum, and on that a latent image is to be formed.

A blade-like charging member for charging a surface of an image bearing member by contacting the image bearing member and by being supplied with a voltage. The blade-like charging member includes a charging portion for effecting electric discharge to the surface of the image bearing member, and a non-charging portion not effecting the electric discharge to the surface of the image bearing member. The non-charging portion is capable of contacting the image bearing member while maintaining an electrically dischargeable gap between the charging portion and the image bearing member. At least a part of the non-charging portion is made of a material having a higher resistance than that of the charging portion so as to prevent electric discharge between the non-charging portion and the surface of the image bearing member.
