Embodiment Construction

[0044] figure 1 It is a front view schematically showing the configuration of the image forming system of this embodiment. The image forming system of this embodiment is composed of an image forming apparatus 1 , an intermediate conveyance apparatus 2 , and a sheet processing apparatus 3 . The image forming device 1 , the intermediate conveyance device 2 , and the sheet processing device 3 are continuously arranged in this order from the upstream side to the downstream side in the conveyance direction of the paper P.

[0045] The image forming apparatus 1 is, for example, an electrophotographic image forming apparatus, and is a so-called tandem color image forming apparatus that forms a full-color image. The image forming apparatus 1 is mainly composed of a document reading device SC, image forming units 10Y, 10M, 10C, and 10K, a paper transport unit 13 , a fixing device 16 , and a control unit 18 .

[0046] The document reading device SC illuminates the image of the documen...

Abstract

A paper humidifier and an image forming system are provided and can inhibit excessive supply of water so as to achieve proper humidification. A first humidifying unit (210A) adopts a structure that anintermediate roller (212A) is provided between a suction roller (211A) and a water supply roller (213A). The intermediate roller (212A) is configured in a manner that the intermediate roller is located above a liquid level of the water stored in a water reservoir (216A), and a kneading part (N1) between the intermediate roller (212A) and the suction roller (211A) is above the water reservoir (216A). In the suction roller (211A), an outer peripheral surface of the roller, which rises out of the water stored in the water reservoir (216A), rotates in a direction away from the water supply roller(213A).

Description

technical field [0001] The present invention relates to a paper humidifying device and an image forming system. Background technique [0002] In image formation by electrophotographic processing, in the fixing process in the process, heat and pressure are used to fuse toner to fix the image on paper. During this fixing process, a phenomenon occurs in which moisture evaporates from the paper due to heat, and a phenomenon occurs in which the paper absorbs moisture from the outside air after fixing. There is a problem with the paper becoming wavy or curled due to evaporation of moisture or absorption of moisture. [0003] Therefore, there has been proposed a method of adding water to paper on which an image is formed to humidify (for example, refer to Patent Document 1). The recording material processing apparatus described in Patent Document 1 includes a moisture supply roller, a moisture amount adjustment roller for contacting the moisture supply roller to adjust the amount...
