ABSTRACT:
A roller assembly for use in an electrostatographic development apparatus to transport developer material through a development zone. The roller assembly includes end cap sections for mounting rotatably to a housing of the development apparatus, and a spincasted sleeve section interconnecting the end cap sections. The spincasted sleeve section includes an outer layer that has a series of non-radial undercuts formed thereinto for retaining developer material being transported. In order to achieve consistent precision at relatively lower costs, the sleeve section is produced by spincasting a desired quantity of filled thermoset material in a simple reusable silicone mold formed and held in a mud frame.
