Patent ID: 7890045

Claim:
A waste toner recovering mechanism comprising: a first rotating member rotating about a first rotation shaft with a rotational driving force; 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; and a one-way clutch which is disposed between an agitation paddle agitating waste toner recovered into a waste toner container 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 relative to 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°.
