ELECTROPHOTOGRAPHIC COLOR PRINTING APPARATUS

摘要

Systems consistent with the present invention provide an electrophotographic printing apparatus (100) that includes a group of developing units (130, 132, 134, 136), a photoreceptor belt (102) having an outer surface (104), and a group of support members, such as rollers (106, 108, 110) operably disposed to support the movement of the photoreceptor belt along a path. The photoreceptor belt (102) has a shape defined, at least in part, by the support members. The shape of the photoreceptor belt has at least two sides (116, 118) meeting at a transfer point (120). The first (116) of the two sides extends at a first angle (124) from the outer surface of the photoreceptor belt to a horizontal axis of the apparatus at the transfer point (120) and the second (118) of the two sides extends at a second angle (126) from the horizontal axis to the outer surface of the photoreceptor belt such that the first and the second angles are each less than 90°C. Each developing unit is disposed adjacent to the first or the second sides of the shape of the photoreceptor belt.
