Abstract
An image forming apparatus includes a mounting portion, an accommodating portion, a remaining toner amount detecting portion, a display portion, and a controller. In a supplying operation, the controller sets a threshold on the basis of a first output value before toner supply from the toner container to the accommodating portion. The controller discriminates whether or not toner in a certain amount or more is supplied to the accommodating portion by comparing the threshold with a second output value after the toner is supplied from the toner container to the accommodating portion. The threshold is a value between the first output value and a third output value when the toner in a total amount accommodated in the toner container that has never been used is supplied to the accommodating portion before supply of the toner, and is closer to the third value than to the first value.
