Image forming apparatus

An image forming apparatus comprising:

• a photosensitive member;
• a developing roller;
• a first motor configured to drive the developing roller;
• a drive-train configured to transmit a driving force of the first motor to the developing roller and including a drive switching unit, wherein the drive switching unit is configured to switch between a transmission state where the driving force is transmitted to the developing roller and a non-transmission state where the driving force is not transmitted to the developing roller;
• a development switching unit configured to switch between a contact state where the developing roller is brought into contact with the photosensitive member and a separated state where the developing roller is separate from the photosensitive member, and configured to operate in conjunction with an operation of the drive switching unit;
• a second motor configured to drive the development switching unit and the drive switching unit;
• a control unit configured to control the first motor and the second motor;
• and
• a current detection unit configured to detect a current flowing through the first motor,
• wherein, in a case where the drive switching unit transitions from the non-transmission state to the transmission state and a magnitude of the current detected by the current detection unit has changed, the control unit is configured to execute a stop operation to stop the second motor before the developing roller is brought into contact with the photosensitive member while driving the first motor.
