An image forming apparatus, comprising:
- a carrier configured to carry a recording medium;
- a power unit configured to provide drive power to the carrier;
- a switch configured to switch an operation state of the carrier between an ON state and an OFF state of a transmission of the drive power from the power unit to the carrier;
- a controller configured to provide a control power to control the switch such that the control power is reduced after switching from the OFF state to the ON state;
- a first detector configured to detect the recording medium at a position before the carrier;
- an insertion opening for inserting the recording medium;
- and
- a second detector configured to detect the recording medium being inserted into the insertion opening,
- wherein the controller increases the control power from a second control power to a first control power, the second control power being provided in response to the detection by the second detector, the first control power being provided in response to the detection by the first detector.
