Abstract
An image forming apparatus includes an image bearing member, a developer container, a first calculator, and a second calculator. The first calculator calculates an amount of the developer supplied to the image bearing member from the developer container, on the basis of an amount of the developer measured by a measuring device after an image forming operation, and an amount of the developer initially contained in the developer container. A controller outputs an information signal relating to the developer amount accumulated in the collection container on the basis of the amount of the developer calculated by the first calculator and the amount of the developer calculated by the second calculator.
