PURPOSE: To provide an image forming device having such transfer structure that a transfer roller and a pretransfer roller are supported on an identical supporting member, a distant between them is kept constant and the positioning thereof with respect to a photoreceptive roller is realized.
CONSTITUTION: Since the transfer roller 2 and the pretransfer roller 3 are supported on the identical supporting member 10 and the supporting member 10 is supported so as to be freely rocked the relative position between the roller 2 and a photoreceptive drum 4 can be adjusted by adjusting the position of the supporting member 10. Besides, since the rollers 2 and 3 are supported on the identical supporting member 10, the distance between them is fixed and the precise arraying state of gears for transmitting driving force between them is maintained even when the position of the roller 2 is adjusted. Besides, such trouble as the tooth skip of the gear can be prevented.
