摘要: A serial tandem image forming system is described which is capable of inhibiting both the degradation of image quality and the reduction of the productivity. This system consists mainly of the control units of upstream and downstream apparatuses. When a preceding sheet differs from the subsequent sheet in sheet type, a control unit for controlling the image forming system has the subsequent sheet stand by at a paper stop roller of the upstream apparatus, and performs the operation of switching the operating states of the upstream and downstream apparatuses in accordance with the sheet type of the subsequent sheet. Also, the control unit predicts the timing of finishing the switching of the operating state, and then re-starts the conveyance of the subsequent sheet, in advance of finishing the switching of the operating state, by controlling the paper stop roller on the basis of the predicted finishing timing.

摘要: Provided is a recording medium detection device which prevents a recording medium from jamming. The device comprises: a first roller and a second roller which nip and transport a recording medium; a roller shaft which rotatably supports the second roller; a shaft support; and a displacement detector. The shaft support supports the roller shaft movably in the thickness direction of the recording medium. The displacement detector detects displacement of the second roller in the thickness direction. The shaft support further supports the second roller movably in the transportation direction of the recording medium through the roller shaft.

摘要: To provide a sheet conveyance device capable of preventing degradation in quality of conveying a sheet and image quality even when a stiffness of the sheet is different between a sheet conveyance direction and a sheet width direction. A sheet conveyance device of an image forming apparatus includes an image forming part that conveys a sheet along a conveyance path; and a stiffness acquisition part that acquires a stiffness of the sheet in a first direction including a component in the sheet conveyance direction by bending the sheet in the first direction, and acquires a stiffness of the sheet in a second direction including a component in the sheet width direction orthogonal to the sheet conveyance direction by bending the sheet in the second direction.
