Abstract
An image forming apparatus including a motor for rotating a stirring member and a cleaner to which a driving force of the motor is transmitted via a transmission mechanism. In a buffer container of a toner replenishment device of a developing device, a gear connected to a restriction member for stirring toner in the buffer container and restricting toner from dropping into a toner conveying section and a cleaning member for cleaning the detection surface of a toner sensor are driven by a motor. A CPU controls a timing at which a clutch stops transmission of the driving force from the motor to the gear, based on a result of detection by a flag sensor that detects an amount of rotation of the gear, and a rotational speed of the motor.
