Image forming apparatus

An image forming apparatus comprising:

• an image forming device configured to form an image on recording paper;
• a resist rollers provided upstream of the image forming device in a predetermined recording paper transport direction and configured to feed the recording paper to the image forming device;
• a first controller includes a first processor and configured to perform rotation control for the resist roller, through the first processor executing a first control program;
• a tilt detection sensor configured to detect a tilt of the recording paper with respect to the transport direction;
• a tilt mechanism configured to tilt a roller shafts of the resist rollers whose initial state is a state where the roller shafts is perpendicular to the transport direction, upstream or downstream with respect to the transport direction;
• and
• a second controller includes a second processor and configured to perform control for causing the tilt mechanism to tilt the roller shaft upstream or downstream with respect to the transport direction based on a detection result of the tilt detection sensor, and causing the tilt mechanism to return the tilted roller shaft to the initial state when the recording paper reaches the resist roller, through the second processor executing a second control program, wherein
• the second controller transmits tilt data indicating a direction and amount of tilt of the roller shaft to the first controller, and
• the first controller corrects a rotation speed of the resist roller based on the direction and amount of tilt of the roller shaft indicated by the tilt data received from the second controller.
