Problems solved by technology

For example, if a higher temperature is expected at the end of the fuser roller, the interval between conveying the recording medium may be longer than normal, so that the temperature at the end of the rotating fuser element may rise below the allowable temperature limit

Embodiment Construction

[0020] In describing the preferred embodiments illustrated in the drawings, specific terminology will be employed for the sake of clarity. However, the content disclosed in this patent specification is not intended to be limited by the specific terms chosen, and it should be understood that each specific element includes all technical equivalents that operate in the same manner. Referring now to the drawings, in which like reference numerals designate like or corresponding parts throughout the several views, and particularly FIG. 3, there is shown a cross-sectional view of a typical construction of an imaging device according to an embodiment of the present invention.

[0021] The image forming apparatus has color electrophotographic print engines 10 connected in series. The tandem color electrophotographic print engine 10 includes four imaging stations 12 corresponding to the four colors yellow, magenta, cyan and black, respectively. Each image forming position 12 includes a...

Abstract

An image forming device, an image fixing device and an image fixing method. The image fixing method adopts an electrophotographic process to fix a toner image on a recording medium, and can effectively control the image fixing temperature. In one example, when recording media narrower than the maximum allowable size are continuously supplied at the image fixing temperature, the interval between the conveyed recording media is controlled to be longer than the default interval in order to maintain the allowable temperature limit, the The default interval corresponds to a recording medium that is longer in the feeding direction to avoid temperature rise at the end of the fixing member in the axial direction.

Description

technical field [0001] The present invention generally relates to an image forming apparatus such as a printer, copier, facsimile machine, etc., which forms an image on a recording medium such as paper, OHP sheet, fabric, etc., and also relates to an image fixing apparatus and an image fixing method, in which The method in which the image on the recording medium is fused by heat and pressure in the nip pressing area between the fusing member and the pressure member. The present invention more particularly relates to an image forming device, an image fixing device and an image fixing method capable of effectively controlling the image fixing temperature. Background technique [0002] From the point of view of printing speed, image quality, cost, etc., most of the imaging devices in the background technology, such as printers, copiers, facsimile machines, etc., adopt electrophotographic technology. The electrophotographic process includes the steps of charging a photoconducto...
