Embodiment Construction

[0035] Embodiments of the present invention will be described below.

[0036] figure 1 It is an external perspective view of an image forming apparatus as an embodiment of the present disclosure.

[0037] The image forming apparatus 1 has a scanner 10 and a printer 20 .

[0038] The scanner 10 is placed on an apparatus casing 90 serving as a frame of the image forming apparatus 1 , and the printer 20 is configured in the apparatus casing 90 .

[0039] figure 2 is shown in figure 1 A schematic diagram of the internal structure of the image forming apparatus showing the appearance in .

[0040] The printer 20 has four image forming sections 50Y, 50M, 50C, and 50K arranged substantially in a row horizontally. In these image forming sections 50Y, 50M, 50C, and 50K, toner images based on toners of yellow (Y), magenta (M), cyan (C), and black (K) colors are formed, respectively. Here, in the common description of these image forming units 50Y, 50M, 50C, and 50K, the symbols Y...

Abstract

The invention discloses a fixing apparatus and an image forming apparatus. The fixing apparatus comprising: a heating section including a belt having a layered structure in which a metal layer is heldbetween nonmetal layers; a pressure section that holds, between the pressure section and the belt, a transported sheet of paper holding the toner image and that applies pressure to the sheet of paper; and a first static eliminating section that eliminates static from the belt while being in contact with a surface of the belt, the surface being the front surface in contact with a toner image or the back surface not in contact with the toner image that is on a side of the first thickness or the second thickness having a smaller thickness when a first thickness from a front surface to metal layer in the belt is compared with a second thickness from a back surface to a metal layer in the belt.

Description

technical field [0001] The invention relates to a fixing device and an image forming device. Background technique [0002] Regarding a fixing device for fixing a toner image on paper by heating and pressing, there is known an electromagnetic induction fixing device that includes a belt having a metal layer sandwiched by a non-metallic layer and heats the belt by electromagnetic induction. Layered structure. [0003] Here, in the fixing device, a phenomenon called electrostatic offset in which a part of the toner moves toward the heating portion may occur. When electrostatic offset occurs, a phenomenon occurs in which an image of the toner that has moved to the heating portion side appears at another position on the paper. Here, some acid-containing paper such as envelopes is distributed. When using paper containing acid components, the possibility of electrostatic offset increases. The charging of the heating part mainly affects the generation of this electrostatic offse...
