Abstract

An image forming apparatus comprises, a collecting member configured to collect waste toner adhered on a conveying belt, a cleaning voltage supplier configured to supply a cleaning voltage to the collecting member, a container having a first contact and configured to contain the collected waste toner, and an attachment part having a second contact configured to contact the first contact. The container is detachably attached to the attachment part. The image forming part further comprises a switch configured such that a switching state is switchable based on an amount of the waste toner in the container. The image forming apparatus generates a detection signal based on a voltage at the second contact to determine whether an amount of the waste toner in the container is greater than a particular amount.
