摘要： An image forming apparatus includes a rotating member, a motor configured to rotate the rotating member, and a marking member having primary and secondary portions. The image forming apparatus also includes a mark sensor configured to detect the primary and secondary portions, and output a primary signal and a secondary signal, and a position sensor configured to determine a rotational position of the rotating member based on a primary reception time of one of the primary and secondary signals that comes immediately after the other of the primary and secondary signals when the position sensor receives the other of the primary and secondary signals at a start of a mark detecting operation. Further, the image forming apparatus includes a motor controller configured to control the motor based on the recognition result and make the rotational position consistent with a target position at a predetermined time during the mark detecting operation.

摘要： After detecting a speed fluctuation pattern per rotation of a photosensitive drum, a process that forms an image based on image data while causing the photosensitive drum to rotate at a nonstandard linear speed is executed as an image forming process by driving a process driving motor that drives the photosensitive drum to curb a speed fluctuation of the photosensitive drum by using a driving speed fine tuning pattern. Before executing the image forming process, a fine-tuning-pattern correcting process is executed for correcting the driving speed fine tuning pattern of the process driving motor, based on the nonstandard linear speed.
