Problems solved by technology

However, the conventional technique does not consider correcting periodic changes in magnification along the sub-scanning direction within the image
Also, if the rotational speed of the polygon mirror is to be changed as in the zoom-in / zoom-out technique, the structure of the control circuit will be more complicated

Embodiment Construction

[0032] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. figure 1 The image forming apparatus 10 related to this exemplary embodiment is shown in . The image forming apparatus 10 is connected to a plurality of client terminals 98 constituted by personal computers (PCs) etc. via a network 96 (such as LAN, etc.), and the image forming apparatus 10 is provided with a document reading device 12 which scans and reads Originals placed on the platen glass. Therefore, the following functions are provided together: a printer function for transferring and forming an image represented by data received from a client terminal 98 via a network 96 (for example, data described in a page description language) on a record such as paper on a medium; and a copier function for transferring and forming an image represented by data obtained by reading a document by the document reading device 12 on a recording medium...

Abstract

This invention provides an image formation device and method. An image-forming device which is equipped with an image-holding member, an exposure section provided with plural light-emitting portions arranged in a first direction, a movement section that relatively moves the exposure section and the image-holding member in a second direction that intersects with the first direction, and a light-emission control section. The light-emission control section causes the plural light-emitting portions to periodically emit light in accordance with image data representing an image that is to be formedon the image-holding member, to form the image on the image-holding member. The light-emission control section varies a light-emission period during formation of the image, so as to correct for periodic fluctuations within the image of at least one of density and magnification ratio in the second direction.

Description

technical field [0001] The present invention relates to an image forming apparatus and method, and more particularly, to an image forming apparatus including an exposure section provided with a plurality of light emitting sections arranged in a first direction and a method of operating such an apparatus. Background technique [0002] In an image forming apparatus that forms an image with an electrophotographic system, because of periodic changes in the peripheral speed of the photoreceptor caused by eccentricity of the photoreceptor serving as an image holding member and / or changes over time in various components in the device, A periodic change in density along a sub-scanning direction of an image formed on a photoreceptor, a periodic change in a scaling factor (magnification) along the sub-scanning direction, and the like may occur. Among the changes over time of the components of the device, for example, changes in the thickness of the surface layer of the photoreceptor, ...
