Embodiment Construction

[0031] Hereinafter, this embodiment will be described in detail with reference to the drawings. figure 1 It is a diagram schematically showing the overall configuration of the image forming system 100 according to this embodiment. figure 2 It is a diagram showing main parts of the control system of the image forming apparatus 1 according to the present embodiment.

[0032] Such as figure 1 As shown, the image forming system 100 is configured by connecting the image forming apparatus 1 and the sheet processing apparatus 2 from the upstream side along the sheet S conveying direction.

[0033] figure 1 , 2 The illustrated image forming apparatus 1 is a color image forming apparatus of an intermediate transfer method utilizing electrophotographic process technology. That is, the image forming apparatus 1 primary transfers the toner images of Y (yellow), M (magenta), C (cyan), and K (black) formed on the photoreceptor drum 413 to the intermediate transfer device 413 . In the ...

Abstract

The invention provides a sheet processing apparatus capable of suppressing a conveyance error between a pushing shaft and a guide section and an image formation system. The sheet processing apparatusincludes: a curl correcting section including a conveying member configured to convey a sheet, and a pushing shaft configured to push the sheet conveyed by the conveying member toward the conveying member, the curl correcting section being capable of adjusting a correction amount of a curl of the sheet by adjusting a pushing amount of the pushing shaft for pushing the conveying member; and a moving guide section configured to guide the sheet toward a pushing position of the sheet in the conveying member, the moving guide section being configured to move along with a pushing operation of the pushing shaft while maintaining a distance from the pushing shaft at a predetermined distance or smaller such that the conveyance error of the sheet is not caused when the moving guide section guides the sheet.

Description

technical field [0001] The present invention relates to a sheet processing device and an image forming system. Background technique [0002] Generally, image forming apparatuses (printers, copiers, facsimile machines, etc.) using electrophotographic technology form electrostatic latent images by irradiating (exposing) a charged photoreceptor drum (image carrier) with laser light based on image data. Then, by supplying toner from a developing device to the photoreceptor drum on which the electrostatic latent image is formed, the electrostatic latent image is visualized to form a toner image. Furthermore, after directly or indirectly transferring the toner image to the paper, the toner image is formed on the paper by applying heat and pressure in the fixing nip to fix it. [0003] In such an image forming apparatus, when the paper is curled during conveyance, post-processing failures such as poor alignment or loading failure will occur. In particular, when the paper is thin ...
