Embodiment 10～12

[0235] In order to fix the obtained solid patch image and each solid patch fixed image obtained by fixing the toner surface temperature ( 241 b ) to 125° C. by heating and pressing without irradiating light to each toner structure For comparison, the color of the solid portion in each image was measured with a fluorescence spectrodensitometer “FD-7” (manufactured by Konica Minolta Co., Ltd.), and the color difference was calculated using the CMC (2:1) color difference formula. Evaluation was performed according to the following criteria, and there was no practical problem if it was ◯ or more.

[0236] (evaluation criteria)

[0237] : color difference is less than 2

[0238] ○: Color difference is 2 or more and less than 3.5

[0239] ×: Color difference is 3.5 or more

[0240]

[0241] On plain paper (basis weight: 64g / m 2 ), the toner adhesion amount is 4g / m 2 conditions to develop the electrostatic latent image. This is performed using a printed matter in which a so...

Abstract

The invention relates to an image forming method, an image forming apparatus, and a toner image fixing apparatus. An object of the present invention is achieved by an image forming method containing the steps of: forming a toner image by developing an electrostatic latent image with a toner; transferring the toner image on a recording medium; and fixing the toner image on the recording medium, wherein the fixing step of the toner image on the recording medium further contains the steps of: irradiating light having a wavelength range of 280 to 480 nm to the toner image; and applying pressure tothe toner image.

Description

technical field [0001] The present invention relates to an image forming method, an image forming apparatus, and a toner image fixing apparatus. More specifically, the present invention relates to an image forming method and the like in which a toner image fixed on a recording medium has good color reproducibility and sufficient fixability in an optical fixing system. Background technique [0002] Conventionally, in the electrophotographic process, for the purpose of shortening operability (Warming-Up Time: WUT), energy saving, and expansion of types of recording media, a fixing system using light (hereinafter, also referred to as "light fixing system") has been proposed. ). [0003] As currently reported photofixing systems, a number of systems that fuse and fix toner to a recording medium by converting light into heat have been proposed. Most of them are systems that perform fusion fixing using light in a long-wavelength region in the infrared range. On the other hand, ...
