Abstract
An apparatus in which a latent image recorded on a photoconductive member is developed with developer material. A developer roller, positioned closely adjacent to the photoconductive member, is arranged to transport the developer material into contact with the photoconductive surface in the development zone. A blade member moves from an operative position to a non-operative position. In the non-operative position, the blade member has the free end portion thereof spaced from the developer roller. This enables the developer roller to transport the developer material into contact with the photoconductive member to develop the latent image recorded thereon. In the operative position, the blade member has the free end portion thereof contacting the developer roller. This prevents the developer roller from transporting the developer material into contact with the photoconductive member to prevent development of the latent image recorded thereon.
