摘要： The present invention is capable of changing the system speed quickly and highly accurately while using a CVT device with an advantage in its quietness to transmit a driving force to rotative parts.Specifically, in the case of using a sheet of thick paper as a recording sheet, the controller changes, for each of the pulleys, the distance between the pulley segments (S204) while starting up the DC motor as the driving source (S202). After that, the controller performs the feedback control on the rotation of the DC motor, based on a detection signal received from the encoder of the load shaft of the driven pulley, to achieve the target rotation speed of the load shaft (S206: NO, S207).

摘要： A mount damper comprises electrode plates placed on a motor side and a support body side respectively, a control unit for adjusting voltage between the electrode plates, and an electrostrictive polymer member for changing a distance between the electrode plates by the voltage therebetween. The electrostrictive polymer member is also an elastic body sandwiched between the electrode plates and has a hardness changeable with a change in the interelectrode distance. A motor is mounted through this mount damper. The control unit adjusts voltage applied between the electrode plates to a value different from a value causing resonance of the motor and the electrostrictive polymer member, thereby absorbing vibration of the motor during rotation thereof, irrespective of a rotation speed. Thus, the mount damper and the image forming apparatus using it can reliably prevent resonance and absorb vibration constantly even if a device selectively uses plural levels of the rotation speed.
