PROBLEM TO BE SOLVED: To provide a form conveyance control method of a continuous paper electrophotographic device which reduces variation in speed of a paper feed motor in acceleration or deceleration. SOLUTION: When the paper feed motor is accelerated or decelerated by varying cycles of a reference clock through a current setting part which increases or decreases the upper limit of a paper feed motor driving current, an encoder mounted on the rotating spindle of the paper feed motor, a reference clock generation part, and a control part which drives the motor so that the encoder signal reaches the reference clock, a present set current value is increased on condition that a reference clock cycle is larger than a present reference clock cycle and decreased on condition that a last reference clock cycle is less than the present reference clock cycle.
