Abstract: An image reading device includes a reader, a transparent member, an opposing member, first and second conveyance rotators, and circuitry. The reader reads a sheet. The transparent member is disposed between the reader and the sheet. The opposing member is disposed facing the reader via the transparent member. The first conveyance rotator is disposed upstream from the reader in a conveyance direction of the sheet. The second conveyance rotator is disposed downstream from the reader in the conveyance direction. The circuitry cause the first conveyance rotator and the second conveyance rotator to convey a cleaning sheet at respective conveying speeds different from each other and bring the cleaning sheet into contact with at least one of the transparent member or the opposing member.

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: An image forming apparatus includes a sheet feeding unit, a detecting unit, and a control unit. The sheet feeding unit feeds a recording material. The detecting unit is disposed on a downstream side of the sheet feeding unit in a conveyance direction of the recording material and detects the recording material. The control unit controls the sheet feeding unit to feed the recording material at a speed. In a case where the sheet feeding unit is feeding the recording material at a first speed and the recording material has not been detected by the detecting unit before predetermined time elapses since the sheet feeding unit began feeding the recording material, the control unit controls the sheet feeding unit, before the recording material is detected by the detecting unit, to feed the recording material at a second speed that is higher than the first speed.
