An image forming apparatus includes an image carrier, a development device, a developer collection device, a detector, and a controller. The image carrier carries a latent image. The development device develops the latent image into a toner image, and includes a developer carrier opposing the image carrier and carrying a developer. The developer collection device collects the developer from the development device when the development device is driven. The detector detects a state in which the developer carrier does not carry the developer. The controller starts driving the image carrier, starts driving the development device to cause the developer collection device to start collecting the developer, and stops driving the image carrier when the detector detects the state in which the developer carrier does not carry the developer, to collect the developer from the development device.
