| 摘要 |
A development apparatus that performs development by forming a magnetic brush using a two-component developer is provided with a developer tank that stores developer; a developer bearing member provided with a development sleeve that carries the developer stored in the developer tank on the outer circumferential face and transports the developer to a development area where the electrostatic latent image on the image bearing carrier is developed, the development sleeve being provided with at least a main pole magnet in which a main pole is formed that faces the development area, and an interpole magnet in which an interpole is formed adjacent to the main pole on the downstream side in a developer transport direction; and a carrier recovery means in which a pushing/bending magnetic pole of the same polarity as the interpole is formed such that magnetic force lines of the interpole in the developer bearing member are pushed/bent to the inside of the developer tank.
