Image forming apparatus and method

摘要

It reduces a moving distance of a recording medium and thereby reduces the moving distance to be secured in an image forming apparatus so as to reduce size of the apparatus by a simple method. It is possible to feed a recording medium 304 at lower speed than normal speed on calibrating of a sensor unit 123 so as to reduce a distance passed by the recording medium 304. It is possible to render the moving distance of the recording medium half by rendering feeding speed on the calibrating half the normal speed.
