ABSTRACT:
An ADU transport roller driving device, an image forming apparatus and an ADU transport roller driving method, in which a phenomenon of a warp does not occur on a succeeding sheet, are provided. There are included one drive motor that drives plural transport rollers to transport sheets in an ADU, a first one-way clutch that transmits only rotation force of the drive motor in a forward direction to an entrance side transport roller disposed at an ADU entrance side in a sheet transport direction among the plural transport rollers, a second one-way clutch that transmits only rotation force of the drive motor in a reverse direction of an opposite direction to the forward direction to an exit side transport roller disposed at an ADU exit side in the sheet transport direction among the plural transport rollers, and an electromagnetic clutch capable of transmitting only the rotation force of the drive motor in the forward direction to the exit side transport roller.
