PURPOSE:To prevent the generation of image shear by forming a transfer material carriage suppressing means in a resupply line to suppress the carriage of a resupplied transfer material to be carried to a transfer material synchronizing carrying means. CONSTITUTION:When interlocking operation of a horizontal resist lower roller 41 is executed, an output body 62 of a driving control spring clutch 61 connected to the roller 41 is also rotated. At that time, the outer periphery of a boss part of the output body 62 is rubbed with the inner periphery of a stopped clutch spring 65, resisting force is generated between them and slight load torque is generated in the output body 62. When the output body 62 is rotated, load is also generated in a resupplied transfer sheet and a pair of resist rollers 22 carry the resupplied transfer sheet against the load torque. Thereby, the carrying speed of the pair of resist rollers 22 is affected and slightly delayed and a transfer image contracted in accordance with the contraction of the transfer image due to the load torque of positive and negative rotation rollers generated in the 1st copying or the contraction of the transfer image due to a fixing part is formed on the resupplied transfer sheet. Consequently, a multiple copy image of high quality whose image shear is reduced can be obtained. |
