Problems solved by technology

[0007] The intermediate transfer belt is produced by processing the elastic material into an endless shape by injection molding, stretching it to a predetermined length in a heated mold, and then cooling it. The length is likely to be generated due to thermal deformation during heating and cooling during the manufacturing process. error
When an incorrect intermediate transfer belt is selected during assembly or maintenance of the image forming device, the tension of the intermediate transfer belt when the holder is in the belt transfer device becomes inappropriate, and the transfer performance of the toner image decreases. , resulting in degradation of image quality

Embodiment Construction

[0017] Hereinafter, the best mode for carrying out the present invention will be described when it is applied to a color image forming apparatus. FIG. 1 is a schematic diagram of a color image forming apparatus to which a belt transfer device according to an embodiment of the present invention is applied. Image forming apparatus 100 includes an image reading unit 200 , an image recording unit 300 , a paper feeding unit 400 , and a control unit 500 .

[0018] The image reading unit 200 includes a document table 201 , a first mirror base 202 , a second mirror base 203 , a lens 204 , and a solid-state imaging device (eg, CCD: Charge Coupled Device) 205 .

[0019] The original table 201 is made of a hard glass plate, and an original is placed on the upper surface. The first mirror base 202 mounts a light source and a first mirror. The second mirror base 203 mounts a second mirror and a third mirror.

[0020] The first mirror base 202 and the second mirror base 203 are free to m...

Abstract

The present invention provides a tape transfer device including a transfer member, a moving member, a detector, and a control unit. The transfer member transfers the toner image from the image carrier onto the intermediate transfer belt. The moving member is free to reciprocate in a predetermined direction, and during the reciprocating movement in the predetermined direction, the transfer member is placed between a transfer position that is in pressure contact with the inner peripheral surface of the intermediate transfer belt and a retreat position that is separated from the inner peripheral surface. Variable Bit. The detector outputs a detection signal corresponding to the position of the moving part. The control unit determines whether the tension of the intermediate transfer belt is appropriate based on the output state of the detection signal during one reciprocating movement of the moving member in a predetermined direction.

Description

technical field [0001] The present invention relates to an image forming apparatus applied to electrophotography, which is used for primary transfer of a toner image carried by an image carrier to an intermediate transfer belt (hereinafter referred to as intermediate transfer belt) made of elastic material. A belt transfer device that secondarily transfers the toner image onto paper (including recording media other than paper such as OHP sheets). Background technique [0002] Among image forming apparatuses such as printers and copiers that form images by electrophotography, there are image forming apparatuses that include a belt transfer device. The belt transfer device includes a transfer member which rotatably supports an intermediate transfer belt made of an elastic material along an endless moving path, and which is in contact with and separable from an image carrier across the intermediate transfer belt. The belt transfer device first transfers the toner image carried...
