摘要： A sheet conveyance apparatus according to an embodiment includes a conveyance roller and a register roller arranged downstream of the conveyance roller along a sheet conveyance path. A sensor unit detects a first deflection amount of the sheet and a second deflection amount of the sheet when the sheet is pressed against the register roller. A movable section is connected to at least one end of the conveyance roller. A control section determines a tilt of a rotation axis of the conveyance roller relative to a rotation axis of the register roller based on a difference in the first and second deflection amounts detected by the sensor unit. The control section controls the movable section to move the conveyance roller so that the rotational axis of the conveyance roller is positioned relative to a rotational axis of the register roller in accordance with the determined tilt.

摘要： An image forming apparatus comprises a conveyance roller, a register roller, a sensor, a movable section, and a control section. The conveyance roller conveys a sheet. The register roller is arranged downstream of the conveyance roller along a sheet conveyance path. The sensor detects a deflection amount of the sheet when the sheet is pressed against the register roller. The movable section is connected to at least one end part of the conveyance roller. The control section controls the movable section to move the at least one end of the conveyance roller based on the deflection amount detected by the sensor, to tilt a rotational axis of the conveyance roller relative to a rotational axis of the register roller.
