Problems solved by technology

However, in the method of JP-A-7-44034, the fixing solution is applied to almost the entire surface of the image area (toner image adhesion area) on the recording medium regardless of the image portion and the non-image portion, so when recording When the medium is fiber-containing paper, curling or wrinkling of the recording medium is noticeable

Abstract

The present invention provides an image forming apparatus that does not cause curls or wrinkles on a recording medium when a toner image is fixed on a recording medium using a liquid fixing solution, and that can reduce the amount of the fixing solution used, and even if the Multi-color toner images can also be fixed in a short time with low power consumption. In an image forming apparatus (1) including a toner image forming section (2), an intermediate transfer section (3), a secondary transfer section (4), a fixing section (5), and a recording medium supply section (6) , from the fixing solution application part (33) contained in the fixing part (5), apply the fixing solution (34) to the image part and the non-image part of the recording medium (7), and make the amount of the fixing solution applied at the non-image part Less than the amount of fixer applied to the image area.

Description

technical field [0001] The present invention relates to an image forming device and a fixing solution coating roller. Background technique [0002] In an electrophotographic image forming device commonly used in copiers, printers, facsimile machines, etc., a photoreceptor with a photosensitive layer containing a photoconductive substance formed on the surface is used, and a charge is applied to the surface of the photoreceptor and charged uniformly. , an electrostatic latent image corresponding to image information is formed by various imaging processes, and the electrostatic latent image is developed with a developer that is provided from a developing mechanism and contains toner to make it a toner image, and the toner image is directly transferred to Printed on recording media such as paper, or transferred on an intermediate transfer medium first, and then transferred to a recording medium. Then, in order to fix the toner image transferred on the recording medium on the r...
