Abstract

PURPOSE:To perform image formation always in the specified position of transfer material by providing a means of storing the timing of operating a feed means for a specified time. CONSTITUTION:The feed control device provided with R-S flip-flop circuits 50 thru 53, a counter 60 which stores the registration timing, a counter 61 which measures the time up to registration, a coincidence detecting circuit 62, a differentiation circuit 63 and an amplifier circuit 64 is provided and is connected to a register clutch 48. Thereby, the feed control unit is so set of the timing for operating a register roller 35 that the leading end of the transfer material being delivered out by a feed roller 33 and the leading end of the image on an insulation drum 24 contributing the transfer become of the specified position relation, stores this for the specified time, and controls the operation of the register roller 35 by the storage value thereof. Hence, no matter the image formation timing contributing to the transfer is at any time, the image may be formed in the specified position of the transfer material and in addition, even when the repetitive transfer is going to be performed from one image, the image may be formed always in the specified position.
