Patent ID: 7792473

Claim:
A development apparatus that, in an image forming apparatus, develops an electrostatic latent image formed on an image bearing carrier by forming a magnetic brush using a two-component developer that includes a toner and a carrier, the development apparatus comprising: a developer tank that stores the developer; a developer bearing member comprising: 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, 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, the interpole magnet being adjacent to the main pole magnet on the downstream side of the main pole magnet in a developer transport direction; and a carrier recovery means disposed on the downstream side of the development area in the developer transport direction, the carrier recovery means comprising a pushing/bending magnet having a pushing/bending magnetic pole of the same polarity as the interpole disposed at a position nearer to the interpole than the other magnetic pole of the pushing/bending magnet such that magnetic force lines of the interpole in the developer bearing member are pushed/bent to the inside of the developer tank, and wherein taking as a reference a state in which a first imaginary line that joins both of the magnetic poles of the pushing/bending magnet and a second imaginary line that joins both magnetic poles of the interpole magnet are orthogonal, the pushing/bending magnet is disposed such that the first imaginary line tilts in a direction that results in the pushing/bending magnetic pole approaching the interpole side.
