Abstract

Official abstract text for this publication.

An image forming apparatus includes a waste toner box, a base, a detection sensor, a counter and a controller. The waste toner box collects toner not transferred to a sheet but remaining on a surface of a photoreceptor. The base is for placing the waste toner box thereon, and a position of the base changes with a weight of the waste toner box placed thereon. The detection sensor detects the position of the base to detect an amount of toner in the waste toner box placed on the base. The counter counts the number of sheets with images formed thereon. The controller determines whether or not to continue image formation on a sheet on a basis of a signal from the detection sensor and the counter.
