Abstract
A transfer roller cleaning apparatus of an electrographic imaging system. A driving roller and a driven roller are rotatably installed in a main body of the electrographic imaging system. A cleaning belt has one end and another end thereof wound around the driving roller and the driven roller, respectively. A guide roller is rotatably installed in the main body of the system to support the cleaning belt between the driving roller and the driven roller. An actuator reciprocates the guide roller with respect to a transfer roller to allow the cleaning belt supported by the guide roller to selectively contact the surface of the transfer roller. Therefore, left-over toner or foreign material stuck to the surface of the transfer roller can be easily and rapidly removed.
