Embodiment Construction

[0045] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0046] First, an image forming apparatus 1000 having a laser fixing apparatus 100 as a first embodiment of the present invention will be described. figure 1 is a schematic diagram showing the configuration of the image forming apparatus 1000 . figure 2It is a schematic diagram showing the configuration of the developing device 24 included in the image forming apparatus 1000 . The image forming apparatus 1000 is a multifunctional machine integrating a copy function, a print function, and a facsimile function, and forms a full-color or monochrome image on a recording medium according to transmitted image information. Image forming apparatus 1000 has three printing modes: copy mode (copy mode), print mode, and facsimile mode. For printing jobs such as external devices of the storage device, a printing mode is selected by a control unit (...

Abstract

The invention provides a laser fixing device adapted to use of two types of light fixable toners having different light absorption characteristics, an image forming apparatus having the laser fixing device, and an image forming method employing the image forming apparatus. A laser fixing device (100) includes a laser light emitting section (110) for emitting laser light and a wavelength conversion section (130) for emitting outgoing light having a wavelength different from the one that incident laser light has.

Description

technical field [0001] The present invention relates to a laser fixing device, an image forming device having the laser fixing device, and an image forming method using the image forming device. Background technique [0002] An electrophotographic image forming apparatus (such as a printer) has a fixing device for fixing an image on recording paper. The fixing device melts the toner constituting the toner image formed on the recording paper to form a toner image. fixed on the recording paper. [0003] As a fixing device, for example, a fixing device of a heat roller type including a fixing roller and a pressure section as described in Japanese Patent Application Laid-Open No. 11-38802 is known. In the heat roller type fixing device, the recording paper bearing the unfixed toner image is sandwiched between the fixing roller having a heating part inside and the pressing part in pressure contact with the fixing roller, and the toner on the recording paper is melted. and fixed...
