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.

Image forming apparatus, image forming method, and image forming program product

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.

Image forming apparatus

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.

Image forming method and apparatus, and a recording medium storing a program for performing an image forming method

The present invention provides 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. A holder is used as means for holding the optical units in row form.

A light-heat conversion in a light-stimulated writing method and associated apparatus include an image recording body having an element, which absorbs an (electromagnetic wave) provided in a surface of a recording body, or in a recording layer formed on an uppermost layer of the recording body having a material exhibiting a thermal changeable character of wettabilty, or in a substrate or an intermediate layer of the recording body. After a liquid is disposed on the recording body by a liquid forming device, light-stimulated writing is carried out, resulting on an enhanced efficiency of light-heat conversion by a light absorbing element.

A data sheet is composed of an upper part and a lower part. The upper part is used as a user interface including a reduced image of contents of a document. The lower part is an interface for a reading device such as a copy machine, including a code obtained by encoding the document. By use of the data sheet, the user can easily distribute or carry an electronic document data with the user. In addition, the user can recognize contents of the electronic document data by looking at the reduced image printed on the data sheet.

Data sheet and information management system using data sheet

Image recording body and image forming device using the image recording body

There is provided an image forming apparatus which fixes ink in a short time without deteriorating clearness or transparency of the ink. An ink image is formed on a recording medium by the ink containing a resin and a solvent miscible with the resin. An ink curing liquid is applied to contact the ink image on the recording medium. The ink curing liquid is miscible with the solvent, and has a molecular weight greater than a molecular weight of the solvent. Alternatively, an ink curing solid is applied to contact the ink image on the recording medium. The ink curing solid has a swelling property with respect to the solvent contained in the ink.

Image forming method and apparatus for rapidly fixing ink on a recording

A recording body is used which includes a base material and a recording material having characteristics of the wettability change by heating, the recording material being coated on the base material so as to form a recording surface. The image forming method includes the steps of a) heating the recording surface of the recording body in liquid; and b) partially heating the recording surface in air so as to form a latent image.

Image forming method and apparatus, and image recording and indicating

An image forming method including the steps of bringing an image-forming liquid in which finely-divided resin particles are dispersed in a dispersion medium into contact with an image-bearing member capable of repelling the dispersion medium of the image-forming liquid, and selectively applying heat and/or pressure to the image-bearing member or the image-forming liquid by use of a heat-application system and/or pressure-application system in accordance with signals corresponding to an image to be formed to deposit imagewise the finely-divided resin particles in the image-forming liquid on the surface of the image-bearing member, thereby obtaining a resin image corresponding to the image on the image-bearing member. In addition, an image forming apparatus for the above-mentioned image forming method is disclosed.
