Abstract: A development system for a reproduction machine includes a pair of augers which mix and transfer the developer mixture to a magnetic roll brush system. A supply auger having a length at least as great as said magnetic brush roll is positioned along a horizontal plane and adapted to transport developer material in a direction so as to supply said material to said magnetic brush roll. The auger has a first portion thereof having an irregular blade edge and wedge shaped paddles to eliminate auger mark print defects.

Abstract: A donor roll (40) for the conveyance of toner in a development system for an electrophotographic printer includes an outer surface (42) of phenolic resin. The resin is doped to a suitable conductivity to facilitate a discharge time constant thereon of less than 300 microseconds. The donor roll is used in conjunction with an electrode structure (41) to provide scavengeless development of an electrostatic latent image on a charge-retaining member (10).

Abstract: The developer unit is adapted to develop a latent image with toner particles. A housing defines a chamber for storing a supply of toner particles. A donor roll includes an electrically non-conductive circumferential surface having a conductivity less than 10 power-8 per ohm-cm and having a central region and opposed marginal regions disposed on either side of the central region. The diameter of the central region is less than the diameter of the opposed marginal regions, the donor roll being spaced from the latent image to from a development zone. An electrode member is positioned in the development zone adjacent opposed marginal regions and spaced from the central regions of the donor roll. The electrode member is electrically biased to detach toner particles from the donor roll to form a toner powder cloud in the development zone with toner particles from the toner cloud developing the latent image.

Abstract: PROBLEM TO BE SOLVED: To supply a developing material to a photoconductive member in a uniform level and at a required speed in a developer unit of a type that the developer material is not trimmed on a top of a magnetic roller. SOLUTION: A first rotatable auger 722 is disposed so as to face a rotatable magnetic roller 720; a second auger 724 is disposed below the first auger 722, and trim blades 746, 750 are disposed around the outer surface 742 of a roller 720 in mutually different inclined postures. When the first auger 722 rotates, a toner which is the developer material is conveyed to the outer surface 742. When the roller 720 rotates, the toner is leveled by the blade 746 at first (preparatory trimming) and then leveled by the blade 750 (main trimming) and the leveled toner is supplied to a photoreceptor belt 710 which is the photoconductive member or further to another magnetic roller. Consequently, trimming can be performed under the roller 720 and the supply amount and speed of the toner can be fixed. COPYRIGHT: (C)2010,JPO&INPIT
