Abstract
A development apparatus for use in an image forming device includes a developer storage chamber for storing developer, a developer carrier having a film of the developer formed thereon, wherein a visible image is formed when the film interacts with an electrostatic latent image, and a developer feed member arranged adjacent to the opening of the developer storage chamber and configured to feed developer from the developer storage chamber to the developer carrier. A developer leakage prevention member is located between the developer feed member and the developer carrier and an adhesive adheres to the developer leakage prevention member in the longitudinal direction of the opening. Also, a layer including an agent is formed between the adhesive and the developer feed member.
