摘要： An image forming apparatus includes: a rotation shaft (71); a movable body (72) that is attached to the rotation shaft (71), that is provided with a cleaning member (73), and that moves with rotation of the rotation shaft (71); a motor M for rotating the rotation shaft (71); a control section (8) for controlling rotation of the motor M; a current detecting section (77) for detecting a current flowing through the motor M; and a time counting section for counting time. Here, the control section is provided with: an overcurrent detection checking function; a time counting function; a predetermined position attainment checking function; a reciprocation control function; an erroneous detection checking function for performing erroneous detection checking operation in which an overcurrent detected while the movable body is moving forward in the reciprocation thereof is checked while the movable body is moving backward in the reciprocation thereof; and a repeating function for performing the erroneous detection checking operation once or a plurality of times in a repeating fashion.

摘要： An image forming apparatus is disclosed which interrupts the power supply to the sensors that are used during image formation when it is impossible to form an image, thereby allowing the image forming apparatus so save energy more effectively. The image forming apparatus controls the power supply to sensors that are used during image formation, other than a heating temperature sensor and fixation control sensors, such that the image forming apparatus interrupts the power supply when switched to the non-fixation operation control state, and supplies power when switched to the fixation operation control state and the temperature detected by the heating temperature sensor is equal to or greater than a predetermined temperature near the fixation temperature.

摘要： An image forming apparatus includes a two-component developing devices for each of a plurality of photoreceptors and a motor for the developing device. A transmission can assume a coupled state where the transmission transmits driving force of the motor to the developing device and a separated state where the transmission does not transmit the driving force of the motor to the developing device. A toner agitating mechanism stirs toner inside the developing device. A permeability sensor detects permeability inside the developing device and outputs a signal according to a ratio of the toner to the carrier. A coupling judging section judges that the coupling state exists when a variation of a signal value outputted by the permeability sensor equals or exceeds a predetermined value and judges that the separated state exists when the variation of the signal value outputted by the permeability sensor is lower than the predetermined value.
