Problems solved by technology

[0003] However, when a pair of ejection rollers and an ejection roller cooling portion are provided on the downstream side of the fixing device in the direction of recording material conveyance, the heating effect of the fixing device causes curling of the recording material, and the cooling effect of the ejection roller is further increased Curl degree of recording material (degree of curl)
Therefore, paper jams are likely to occur during conveyance of the recording material, and the storage performance of the recording material will be reduced

[0035] Hereinafter, a first exemplary embodiment of the present invention is explained with reference to the drawings.

[0036] FIG. 1 is a view schematically showing the configuration of an image forming apparatus according to an exemplary embodiment of the present invention. The image forming apparatus shown in FIG. 1 is an intermediate transfer type image forming apparatus generally called a tandem type. The image forming apparatus includes a plurality of image forming units 1Y, 1M, 1C, and 1K that electrophotographically form toner images of various colors. In addition, the image forming apparatus includes a primary transfer portion 10 that sequentially transfers (primary transfer) the toner images of the respective colors formed by the image forming units 1Y, 1M, 1C, and 1K to an intermediate transfer Take 15 on.

[0037] Further, the image forming apparatus includes a secondary transfer portion 20 that collectively transfers (secondary transfers) the overlapping toner ...

Abstract

An image forming apparatus includes: a fixing section that heats an image formed on a recording material to fix the image to the recording material; a first cooling section that cools the recording material to which the image is fixed; and a second cooling section that cools the recording material from an opposite side of a side, to which the image is fixed, of the recording material before the first cooling section cools the recording material.

Description

technical field [0001] The present invention relates to image forming apparatuses such as copiers and printers and methods of cooling recording materials in image forming apparatuses. Background technique [0002] There is known an image forming apparatus including: a fixing device for thermally fixing unfixed developer to a surface of a recording material by passing the recording material carrying the unfixed developer between a pair of rollers at least one pair of discharge rollers for discharging the recording material passing through the fixing device to the outside of the image forming apparatus; and a discharge roller cooling portion for cooling the discharge rollers so as to prevent development on the recording material The toner (toner image) is peeled off by the discharge roller (for example, see JP-A-7-181767). [0003] However, when a pair of ejection rollers and an ejection roller cooling portion are provided on the downstream side of the fixing device in the di...
