US 10,308,452 B2 · Image forming apparatus

Abstract

An image forming apparatus includes a stacking unit, an access detecting unit, a malfunction detecting unit, a counting unit, and a process deciding unit. The stacking unit receives, as stacked, a recording material. The access detecting unit detects an access to the stacking unit by an operator. The malfunction detecting unit detects that a conveyance malfunction of the recording material has occurred on a conveying path guiding the recording material supplied from the stacking unit. The counting unit counts, after the access detecting unit detects an access to the stacking unit by the operator in a state that the malfunction detecting unit does not detect that the conveyance malfunction has occurred, the number of the conveyance malfunction detected by the malfunction detecting unit. The process deciding unit decides a process to address the conveyance malfunction based on the number of the conveyance malfunction counted by the counting unit.
