Abstract
An image forming apparatus includes an image bearing member, a developing device configured to develop an electrostatic image formed on the image bearing member into a toner image, and an exchangeable developer container configured to supply the developer into the developing device. A content sensor detects information relating to a toner content in the developing device, and an exchange detecting portion detects an exchanging operation of the developer container. A controller controls a supplying operation for supplying the developer from the developer container to the developing device on the basis of a detection result of the content sensor and executes a developer supplying mode for supplying developer prohibiting an image forming operation. The controller controls the supplying operation so as to permit the image forming operation without executing the developer supplying mode until an amount of formed images reaches a predetermined level.
