Abstract
In an image forming apparatus and method using a stepping motor for feeding a recording paper, the stepping motor is driven based on a single a line feed control pattern without switching control patterns. An excitation phase counter MPC indicative of a present exciting phase data is compared with a predetermined fixed exciting phase data. If both data coincides, a recording by a recording head is started at the same time the recording paper is advanced by the stepping motor. If both data differs from each other, the stepping motor is driven until both data coincides and thereafter the recording is started with a further driving of the stepping motor. Thus, the data recording on the recording paper is started at the same time as exciting the fixed exciting phases.
