<P>PROBLEM TO BE SOLVED: To prevent the generation of image omission and winding on the tip part of a recording material in a carrying direction in an one-face image formation mode and on the rear end part of the recording material in the carrying direction of the second face in a both-face image formation mode. <P>SOLUTION: The margin width (a) of the tip of the recording material in the carrying direction or the margin width (b) of the rear end of the recording material in the carrying direction is set by a margin width variable setting means 12a. A control means 13 controls the operation of a 1st operation means 43e and a 2nd operation means 44e in a direction for allowing the recording material separation members 43a, 44a to abut a rotor or in a direction for separating the members 43a, 44a from the rotor in accordance with the tip margin width or the rear end margin width of the recording material in the carrying direction which is set by the variable setting means 12a at the time of fixing processing in the one-face image formation mode and fixing processing in the both-face image formation mode. Consequently the generation of image omission and winding on the leading part of the recording material in the carrying direction in the one-face image formation mode and the rear end part of the second face in the carrying direction in the both-face image formation mode can be prevented. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
