Abstract

An example binary ink developer (BID) assembly includes a housing, a developer roller, a squeegee roller, and a guard member. The developer roller receives ink and transfers a portion of the ink to a photoconductive member. The squeegee roller rotates and regulates a film thickness of ink on the developer roller. The squeegee roller includes a curved circumference. The guard member includes a conforming end disposed across from the squeegee roller. Further, the conforming end has a concave shape corresponding to a portion of the curved circumference of the squeegee roller.
