摘要:
An image is formed by dividing rasterized original image data into regions in accordance with N recording heads, and scanning a recording body by simultaneously irradiating recording beams from the N recording heads. Corrected image data divided into regions in accordance with the recording heads are generated by changing the rasterized original image data based on information including positional displacements of the recording beams, so that the positional displacements are corrected. Scanning information is generated based on the positional displacement information. The scanning information includes positions and orders for the recording beams to scan the recording body to record the corrected image data.

Described herein is a light source apparatus in which wasteful cost increases can be suppressed during the manufacture of various types of light source apparatuses and replacement of a broken light source can be performed at low cost, a recording apparatus using the light source apparatus, and an image forming apparatus comprising the recording apparatus, a plurality of optical units comprising optical members (a light source element and a lens) for outputting a single beam are combined separably in row form, and a holder used as means for holding the optical units in row form.
摘要:
An image forming method is performed by an image forming apparatus having a head mounting a plurality of writing units that form an image on a recording medium. The writing units are aligned in a sub-scanning direction perpendicular to a main-scanning direction. A part of the image is formed on the recording medium by the writing units, the part of the image forming a line extending in the main-scanning direction. The step of forming a part of the image is repeated while shifting the writing units in the sub-scanning direction by a predetermined amount of shift. The amount of shift of the wiring units is varied so that an amount of misalignment in a connecting portion between the parts of the image on the recording medium is reduced.

摘要:
A raster image processing method is adapted for a rasterizing device which converts original image data into raster image data suitable for an image forming device having a plurality of recording heads and performing recording of an image on a recording medium using the plurality of recording heads. The original image data is divided into image data elements for areas of the recording medium for the plurality of recording heads to perform the recording of the image respectively. The divided original image data elements are rasterized into the raster image data suitable for the image forming device.

摘要:
An optical light source unit includes a light source that emits a beam, and a collimate lens that collimates the beam and executes imaging on an imaging surface. The beam substantially has light intensity of Gauss distribution in a cross section after passing through the collimate lens. A radius of the beam in a cross section is larger in a sub scanning direction than that in a main scanning direction at a beam waist and on the imaging surface. An entry angle of the beam entering the imaging surface with a normal line of the imaging surface is larger than a diverse angle of the beam returning and diverging from the imaging surface.
