Waste toner recovering mechanism and image forming apparatus

An image forming apparatus comprising:

• a rotational driving source;
• a first rotating member rotating about a first rotation shaft with a rotational driving force from the rotational driving source;
• a second rotating member rotating about a second rotation shaft parallel to the first rotation shaft;
• a linking member of which one end is rotatably supported at a position, which is decentered from the first rotation shaft, in the first rotating member and of which the other end is rotatably supported at a position, which is decentered from the second rotation shaft, in the second rotating member;
• a waste toner container containing waste toner;
• an agitation paddle agitating the waste toner recovered into the waste toner container;
• and
• a one-way clutch which is disposed between the agitation paddle and the second rotating member and which transmits a rotational driving force from the second rotating member rotating in a first rotation direction to the agitation paddle but does not transmit the rotational driving force from the second rotating member rotating in a second rotation direction opposite to the first rotation direction to the agitation paddle,
• wherein the support positions of the linking member in the first and second rotating members and the length of the linking member are set so that a rotation angle range of the second rotating member while the first rotating member rotates in one turn is narrower than 180°.
