Abstract

An image forming apparatus capable of performing a supplying operation for supplying toner from a supply container detachably mountable thereto includes an image bearing member, a developing member, a developing container, a detecting portion, a notifying portion, and a controller for carrying out control so as to cause the notifying portion to notify a timing to perform a toner supplying operation when a toner amount detected by the detecting portion is smaller than a threshold. The controller carries out control so as to set the threshold to a first threshold in a case where a print ratio after the last supplying operation is a predetermined print ratio or more and to set the threshold to a second threshold higher than the first threshold in a case where the print ratio is less than the predetermined print ratio.
