In a control device of an improved image forming member drive device of an automatic drawing apparatus, the image forming member is controlled in two modes, i.e., a position control mode and a pressure control mode. In the position control mode, the image forming member is controlled in a closed loop upon receipt of a feedback signal of its position in the vertical direction. In the pressure control mode, the image forming member is controlled in an open loop. Accordingly, the image forming member is located accurately and at high speed at a prescribed stop position at the beginning of the drive.
