Claim:
A development apparatus configured to develop a latent image on a latent image bearer using a developer, which includes a toner and a carrier, the development apparatus comprising: a first developer chamber configured to store and supply the developer; a first developer bearer configured to convey the developer supplied from the first developer chamber to a first development domain, defined by a portion of the first developer bearer facing the latent image bearer, to develop the latent image on the latent image bearer with the developer; a second developer bearer configured to convey the developer passing through the first development domain to a second development domain, defined by a portion of the second developer bearer facing the latent image bearer, to develop the latent image on the latent image bearer with the developer; a second developer chamber configured to recover the developer passing through the second development domain and store the recovered developer; a transfer prevention member provided between the second developer chamber and the second developer bearer to reduce a transfer of the developer from the second developer chamber to the second developer bearer; a first conveyance member configured to convey the developer in the first developer chamber along a longitudinal direction of the first developer bearer; and a second conveyance member configured to convey the developer in the second developer chamber along a longitudinal direction of the second developer bearer, and to rotate in an opposite direction to a direction in which the second developer bearer rotates in a domain where the second conveyance member faces the second developer bearer, wherein the transfer prevention member is provided directly between the second developer bearer and the second conveyance member.
