PROBLEM TO BE SOLVED: To uniformize a load applied to a cleaning blade even if any image including an image in which the same pattern continues with respect to the axial direction of a photoreceptor drum being an image carrier is formed.SOLUTION: An image formation apparatus comprises: a cleaning blade which recovers toner from an image carrier to a waste toner storage part; an auxiliary cleaning part which rotates on the upstream side of the cleaning blade in the movement direction of the image carrier and recovers the toner from the image carrier to the waste toner storage part; and a waste toner screw which has a turnable spiral part extending in the rotation shaft direction of the auxiliary cleaning part and conveys the toner recovered to the waste toner storage part to one end side in the width direction of the image carrier with turning of the spiral part. The waste toner screw has a toner holding member for capturing and holding the toner from the waste toner storage part on a peripheral surface of the spiral part and turns the toner holding member while bringing it into contact with the auxiliary cleaning part.SELECTED DRAWING: Figure 4 |
