Abstract
An apparatus in which a latent image is developed with developer material. An applicator roller has developer material adhering releasably to at least a portion of the exterior surface thereof. The applicator roller rotates and translates from an non-operative position spaced from the latent image to an operative position closely adjacent the latent image. In this way, the applicator roller transports developer material to the latent image. After development is completed, rotation and translation of the applicator roller is reversed to return the applicator roller to the non-operative position terminating development. An apparatus of this type is used in a multicolor electrophotographic printing machine wherein successive latent images are developed with different color developer materials and the respective developer materials are prevented from co-mingling on the same latent image.
