Embodiment Construction

[0041] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

[0042] figure 1 is a schematic configuration diagram of an image forming apparatus as an exemplary embodiment of the present invention.

[0043] An image forming apparatus forms a color image using toners of four colors, and the image forming apparatus includes an image forming apparatus that outputs images of colors such as yellow (Y), magenta (M), cyan (C), black (K), etc. Electrophotographic image forming units 10Y, 10M, 10C, 10K and an intermediate image transfer belt 11 opposed to the image forming units.

[0044] The intermediate image transfer belt 11 has an endless shape, and is tensioned by a rotating opposing roller 15 , a regulating roller 16 that regulates a deviation in the width direction of the intermediate image transferring belt 11 , and two support rollers 17 and 18 . In addition, the opposing roller 15 is driven so that the peri...

Abstract

Provided is a fixing device including a fixing belt that is formed in an endless shape, is driven to rotate, and includes an outer circumferential surface pressed to a recording sheet holding a toner image, and a thin plate shaped heating member that contacts with an inner circumferential surface of the fixing belt to generate heat and heats the fixing belt, wherein the heating member is supported to be fixed at one end portion in a circumferential direction of the fixing belt, contacts with the fixing belt along the circumferential direction, is elastically deformed so that a shape of the heating member is restrained by the fixing belt, and is pressed to the circumferential surface of the fixing belt by an elastic repulsive force.

Description

technical field [0001] The present invention relates to a fixing device and an image forming device. Background technique [0002] In an electrophotographic image forming apparatus, toner is attached to a latent image by an electrostatic potential difference to visualize the latent image, and the formed toner image is transferred onto a recording medium. In addition, the toner image is fixed on the recording medium by a fixing device. As a fixing device, widely known is a fixing device in which a heated fixing member presses a toner image on a recording medium and heats and presses the toner image. When the recording sheet is supplied to the fixing device, it is necessary to heat the fixing member to a temperature at which fixing can be performed. Therefore, it takes a while to heat the fixing member to a fixable temperature when an image forming operation is started, and in order to reduce the required time, it is common practice to keep the fixing member in a standby sta...
