DEVELOPING STATION WITH CROSS CONVEYANCE

摘要

A printer or copier has a developer station with a toner dispenser in which the toner is fed from a toner box to a transverse transport above a dosing apparatus. The transverse transport includes a helix driven by a drive mechanism. The helix has a pitch H that varies along its length or a thickness D that varies along its length so that the speed of conveyance in the transverse direction decreases over the conveyance path. The rotational speed of the helix is variable by adjustment of the effective length of a drive arm or an extent of an eccentric.
