ABSTRACT:
An apparatus of the invention includes a reciprocating means for reciprocating a predetermined amount of recording paper in the feed and rewinding directions of the recording paper, and is designed such that at least when rolled recording paper is newly set at a predetermined position, a reciprocal operation of the recording paper by the reciprocating means is performed a plurality of times prior to image recording. In this apparatus, when a color image is to be recorded, color misregistration due to a ramp of the recording paper can be prevented. If a means for generating a ramp correction end signal and a means for cutting a recording paper leading end upon completion of ramp correction are added, a further useful apparatus can be realized.
