摘要： An image forming apparatus includes an electrostatic latent image carrier carrying an electrostatic latent image and a development unit that develops the electrostatic latent image. The development unit includes a developer carrier, first, second, and third developer conveyers, and an opening area. The developer carrier is disposed opposing to the electrostatic latent image carrier. The first developer conveyer supplies a developer to the developer carrier. The second developer conveyer conveys the developer, and transports the developer to the first developer conveyer at a downstream side of the second developer conveyer. The third developer conveyer collects the developer, conveys the developer, and transports the developer to the second developer conveyer in a downstream side of the third developer conveyer. The opening area, disposed higher than a lowermost point of the first developer conveyer, allows the developer to drop from the first developer conveyer to the second developer conveyer.
