ABSTRACT:
An image forming apparatus has a locking mechanism and a detecting switch. The locking mechanism locks a drive mechanism not to drive a waste toner container when no waste toner container is loaded in a predetermined place, and releases and thus allows the drive mechanism to drive the waste toner container when the waste toner container is loaded in the predetermined place. The detecting switch outputs, in response to the locking mechanism, a detection signal which varies depending on whether the waste toner container is loaded in the predetermined place. A transporting mechanism for transporting waste toner to the waste toner container is also locked in linkage with the locking mechanism. Consequently, the image forming apparatus has a simple structure and is low-cost and free from faulty operations in judging whether the waste toner container is loaded in the predetermined place and in preventing a faulty transportation of the waste toner to the waste toner container.
