Abstract
Systems consistent with the present invention provide an electrophotographic printing apparatus that includes a group of developing units, a photoreceptor belt having an outer surface, and a group of support members operably disposed to support the movement of the photoreceptor belt along a path. The photoreceptor belt has a shape defined, at least in part, by the support members. The shape of the photoreceptor belt has at least two sides meeting at a transfer point. The first of the two sides extends at a first angle from the outer surface of the photoreceptor belt to a horizontal axis of the apparatus at the transfer point and the second of the two sides extends at a second angle from the outer surface of the photoreceptor belt to the horizontal axis such that the first and the second angles are each less than 90°. Each developing unit is disposed adjacent to the first or the second sides of the shape of the photoreceptor belt.
