ABSTRACT:
In an image forming apparatus of transverse transfer type, toner images, carried by a toner-image carrying member extended by a plurality of rollers in a direction perpendicular to a direction of feed of printing paper, are transferred by a transfer opposed roller to the printing paper in a direction perpendicular to the direction of feed of the printing paper to be fixed. Among the rollers extending the toner image-carrying member, at least one of those rollers except for the transfer opposed roller, which comes closest to the transfer opposed roller at starting and terminal ends of a longest path of movement of the transfer opposed roller, respectively, is provided at a position spaced from a transfer surface of the printing paper, to which the toner images are transferred, by a distance larger than a diameter of the transfer opposed roller. With this construction, a non-transfer region, in which the transfer opposed roller can not move, is reduced, and therefore a body of the image forming apparatus can be made smaller in size.
