ABSTRACT:
An image formation apparatus includes a cleaning device capable of coming into and out of contact with the front surface of a toner image carrier which rotates with toner images adhering on its front surface, and for removing toners adherent on the front surface of the toner image carrier during the contact. A toner reception portion is disposed on a downstream side than the contact position between the cleaning device and the toner image carrier as viewed in the moving direction of the front surface of the toner image carrier, and it is partitioned into a plurality of chambers by a partition plate which extends in a direction substantially orthogonal to the moving direction of the front surface of the toner image carrier.
