Abstract
An image forming apparatus includes an image carrier, a cleaning blade, a motor, and a controller. The image carrier carries a toner image. The cleaning blade is located in contact with the image carrier. The motor drives the image carrier so as to perform reverse rotation and forward rotation. The controller measures a first torque of the image carrier during the reverse rotation, and a second torque of the image carrier during the forward rotation, on a basis of a current value of the motor. The controller calculates an amount of a substance stuck to a surface of the image carrier, on a basis of a measurement result of the first torque and the second torque.
