Document Type and Number:
Japanese Patent JP2020197684
Kind Code:
A
Abstract:
To provide an image forming apparatus that can certainly remove an aggregate from a cleaning member, and a technology related to the same.SOLUTION: An image forming apparatus comprises: an image carrier (for example, transfer belt 21); and a cleaning member (for example, cleaning blade 2) that scrapes off a residual toner on the transfer belt 21 in association with the relative movement of the transfer belt 21. The image forming apparatus executes a maintenance operation to remove an aggregate generated between the transfer belt 21 and the cleaning blade 2. The maintenance operation includes a patch forming operation to form toner images (patch images P50) for removing the aggregate on the transfer belt 21, and a moving operation to causing the transfer belt 21 to advance toward the cleaning blade 2 to cause the patch images P50 on the transfer belt 21 to collide with the cleaning blade 2. An edge E1 on the downstream side in the advance direction D1 of the patch image P50 extends in a direction C1 not perpendicular to the advance direction D1.SELECTED DRAWING: Figure 3
