An image forming apparatus includes a developing device for developing a latent image formed on an image bearing member. The developing device is movable between a developing position wherein it is effective to develop the latent image and a developer collecting position wherein the developer within the developing device can be removed therefrom and collected. The developing device can take one of those positions. When the developer is to be removed and collected from the developing device, the developing device is moved to the collecting position, and then the developer is removed and collected from the developer disposed at the developer collecting position.
