Abstract
An image-forming machine comprising a rotary drum and a cleaning means which removes the toner remaining on the peripheral surface of the rotary drum. The cleaning means includes a support member that extends in the direction of center axis of the rotary drum, a blade-holding member that is mounted on the upper surface of the support member and extends in the direction of center axis of the rotary drum, and a cleaning blade that is held by the blade-holding means and extends in the direction of center axis of the rotary drum. The blade-holding member is allowed to swing on the swing axis that extends in a plane which is substantially perpendicular to the center axis of the rotary drum. An acute angle .alpha. is defined between the cleaning blade and a tangential line of the drum at a portion where the front end of the cleaning blade that is pushed comes into contact with the peripheral surface of the rotary drum, on the downstream side as viewed in a direction in which the rotary drum rotates. Restriction members are attached to the support member at both ends thereof in the direction of the center axis, the restriction members having restriction portions opposed, while maintaining…
