Document Type and Number:
Japanese Patent JP5747870
Kind Code:
B2
Abstract:
An image forming apparatus includes a secondary transfer belt that rotates, an imaging unit for forming a patch image of toner on the secondary transfer belt, and an upstream brush and a downstream brush coming into contact with the secondary transfer belt in a rotating state to remove the patch image from on the secondary transfer belt. A length p of the patch image formed by the imaging unit along a rotational direction of the secondary transfer belt, a distance b1 over which the secondary transfer belt rotates while the upstream brush makes one turn, and a distance b2 over which the secondary transfer belt rotates while the downstream brush makes one turn satisfy an expression: p≰|b1−b2|.
