摘要 |
<p>A power transmitting device (20) that allows a rotation driving unit (31) to stably rotate at a constant angular velocity while overcoming an effect of backlash of a gear which is an element to transmitting power, a drive transmitting apparatus of an image forming apparatus that employs the power transmitting device, and an image forming apparatus that employs the power transmitting device. The power transmitting device includes a weighted rotor (21) that has a weight larger than the rotation object (10) and is connected to the rotation object to rotate along with the rotation object; and a viscous member to reduce a rotation force of the weighted rotor due to a viscosity of a fluid filled therein. The power transmitting device prevents change of the rotation speed of the rotation object due to a gear backlash by using the weight of a weighted rotor and a viscous braking force of a damping grease, and the anti-backlash function can be maintained during a long period of operation. Accordingly, when the power transmitting device is applied to a drive transmitting apparatus of an image forming apparatus, an image forming apparatus forming stable images can be realized.</p> |
