<p><P>PROBLEM TO BE SOLVED: To prevent the generation of image trouble when carrying double-surface printed paper sheets to a paper ejection carrying route through a selector guide, and to prevent a printing surface of a following paper sheet from being contaminated. <P>SOLUTION: The selector guide 20 of the image forming device is structured to change posture thereof between a first posture H1 for guiding the paper sheets P to the paper ejection carrying route 151 with the predetermined drive of a first and a second actuators 40 and 50, a second posture H2 for guiding the paper sheets P to a return carrying passage 163, and a third posture H3 for nearly canceling abutment thereof on the carried paper sheets P. A control unit 70 sets the selector guide 20 to the first posture H1 in the case of the paper sheet P, to which transferring processing is performed in double surfaces, and thereafter, performs control to change posture of the selector guide 20 to the third posture H3 through the first and the second actuators 40 and 50 immediately after beginning to guide the paper sheets P with the selector guide 20. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
