Embodiment 1

[0106] (structure) under the following conditions, in figure 2 Experiments were performed in the configuration shown.

[0107] Pressure roller (aluminum t=0.6, )

[0108] Fixing roller (made of sponge layer t=4, PFA tube t=0.03)

[0109] Pressure roller (aluminum t=0.6, , rubber layer t=0.2, PFA tube t=0.03)

[0110] Heating roller heater (halogen 900W)

[0111] Pressure roller heater (halogen 300W)

[0112] In this case, the set temperature of the heating roller was 200°C.

[0113] (result)

[0114] The heating period to reach 150°C was 35 seconds.

[0115] In the paper transfer experiment, the recording paper was separated in a direction away from the fixing surface.

[0116] In the case of 100,000 sheets, the heating roller was slightly contaminated with toner.

Abstract

A fuser device includes a fusing member including an elastic layer on a surface side thereof and a cylindrical curved surface portion having a predetermined diameter, a heating member including a cylindrical curved surface portion having a predetermined diameter, the heating member having contact with the fusing member and heating the fusing member, and a pressure member including an elastic layer on a surface side thereof and a cylindrical curved surface portion having a predetermined diameter, the pressure member pressing the fusing member.

Description

[0001] This application is based on and claims priority from Japanese Patent Application No. 2007-326346 filed on December 18, 2007, the entire disclosure of which is incorporated herein by reference. technical field [0002] 【0001】 [0003] The present invention relates to a fixing device and an image forming device including the fixing device. Background technique [0004] 【0002】 [0005] An electrophotographic device that forms an image by using toner is used as an image forming device such as a copier, a facsimile or a printer. This image forming apparatus includes a fixing device that fixes a toner image transferred onto a recording medium such as a sheet of recording paper by applying heat and pressure to the recording paper. [0006] Recently, there has been an increasing demand for resource conservation and energy conservation in order to protect the environment. This demand is no exception in image forming apparatuses using electrophotographic methods. Research ...
