Abstract: An image forming apparatus comprises a first roller, a second roller and a control section. The first roller is arranged on a conveyance path of a sheet. The second roller is arranged downstream side of the first roller in the conveyance path. The control section calculates a deflection amount of the sheet nipped by the first roller and the second roller based on a conveyance speed of the sheet conveyed along the conveyance path, and controls a rotation speed of at least one of the first roller and the second roller based on the calculated deflection amount.

Abstract: An image forming apparatus according to an embodiment includes a first roller arranged on a conveyance path of a sheet and a second roller arranged downstream of the first roller in the conveyance path. A control section calculates a deflection amount of the sheet nipped by the first roller and the second roller based on a conveyance speed of the sheet conveyed along the conveyance path. When the calculated deflection amount is smaller than a predetermined lower limit value, the control section increases the rotation speed of the first roller and decreases the rotation speed of the second roller.

Abstract: In accordance with one embodiment, an image forming apparatus comprises a fixing device and a control section. The fixing device is provided with a fixing roller for conveying a sheet. The control section changes the rotation speed of the fixing roller based on a shrinkage rate of the sheet before and after the passing of the sheet through the fixing device. The control section changes, according to the shrinkage rate, the rotation speed of the fixing roller in the second and the following fixing processing carried out by the fixing device in a case in which the same sheet passes through the fixing device more than twice.

Abstract: According to one embodiment, A cleaning device includes a cleaning blade, a support section, a container and an elastic sheet. the support section supports the cleaning blade while pressing an end portion of the cleaning blade to a cleaning object surface. the container has an opening portion at a side opposite to the cleaning object surface and contains a removal object scraped from the cleaning object surface by the cleaning blade. one end of the elastic sheet is fixed to a peripheral portion of the opening portion of the container. the other end of the elastic sheet is in contact with a non-opposite surface as a surface of the cleaning blade at a side not opposite to the cleaning object surface. the elastic sheet guides the removal object scraped from the cleaning object surface by the cleaning blade into the container.
