CONTROLLING METHOD FOR DRIVE OF STEPPING MOTOR

摘要

PURPOSE:To reduce a displacing angle due to a load at a rotor and a stator of a stepping motor. CONSTITUTION:A method for controlling a drive of a stepping motor of an image forming apparatus has the steps of carrying carrier formed of toner image or a transfer sheet to rotatably drive it to drive the carrier for conveying a carrier to be conveyed by a stepping motor, and comprises the steps of controlling to correct a current flowing to a stepping motor 51 at a rotor displaced angle of the motor 51 by a system control plate 55 and an intermediate transfer belt drive motor control plate 67 at a current flowing to the motor 51.
