IMAGE FORMING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2010/026706

Kind Code:

A1

Abstract:

A system speed is changed quickly and precisely while a CVT device excellent in quietness being used in a running transmission passage of a rotor. If cardboard is used as a recording sheet, a DC motor acting as a running source is started (at S202). During this start, a pair of pulley split bodies in each pulley are changed in distance (at S204) so that the CVT device may take a target reduction ratio. On the basis of the detection signal of an encoder of the load rotation shaft of a driven pulley, the rotation of the DC motor is then feedback-controlled (at S207, if NO at S206) so that the rotation speed of the load rotation shaft may be a target value.
