ABSTRACT:
A transfer roller apparatus for use for example in an electrographic copier including a dielectric member adapted to carry electrostatically developed marking particle images on successive image receiving areas. The transfer roller apparatus, is driven to synchronize transfer roller rotation with dielectric member movement for accurate transfer of marking particle images to a receiver member on such roller peripheral surface. The roller transfer apparatus includes a gear train having a first gear coupled to a rotational motive source and a last gear coaxially coupled to the transfer roller. The transfer roller is articulatable to a first position in operative relation with the dielectric member, a second position in operative relation with a cleaning mechanism for the peripheral surface of the roller, and a third rest position intermdiate the first and second positions. Articulation of the transfer roller is effective about an axis which is coincident with an intermediate gear in the gear train whereby the gears in the gear train remain in mesh during articulation of the roller to maintain the synchronous relationship between the roller and the dielectric member.
