<P>PROBLEM TO BE SOLVED: To realize an image forming device capable of suppressing toner image disturbance and forming a satisfactory image. <P>SOLUTION: An image forming device 1 has a belt movement regulation part 28 for regulating movement of the transfer belt 8 so that the transfer belt 8 may not move to the side of a backup roller 81 by being pushed by a sheet P during secondary transferring. The transfer belt 8 can be prevented from moving to the side of the backup roller 81 even when a rear end of the sheet P having rigidity such as cardboard collides with the transfer belt 8, and a gap in which electric discharge may occur between the sheet P and the transfer belt 8 can be prevented from being generated; thereby enabling suppressing toner image disturbance due to electric discharge and forming a satisfactory image. <P>COPYRIGHT: (C)2013,JPO&INPIT |
