Abstract: In a single component development system for use in electrophotographic apparatus, toner particles are moved from a toner hopper or dispenser cartridge (86) to a developer housing (80) and onto a donor roller (74) A rotating holey tube toner agitator (88) is modified to incorporate structure or grooves (106) on the outer peripheral surface. Further, by placing a shrouded toner dispense auger (82) inside the holey tube, the development system architecture stays compact but the delivery of toner powder and the pre-load of toner on the donor roller are improved. With more efficient pre- load, agitator rotational speed and bias can be reduced, leading to less toner effluents emanating from the developer housing without adversely affecting the cycle-to-cycle reloading of the donor roller with toner.

Abstract: A surface layer on an imaging member has a surface roughness which reduces the force necessary for blade cleaning, reduces blade edge tuck, reduces blade/substrate friction, inhibits the formation of toner-type deposits on the imaging surface, and/or reduces or eliminates light interference patterns resulting from coherent light, for example, from a raster output scanner. The surface roughness comprises a lateral roughness of between about 1 micrometer and about 200 micrometers, and a vertical roughness less than or equal to about 1 micrometer. The roughness may be defined by asperites formed by circulation patterns formed in the layer during drying or it may be defined by hemispheric dots of the overcoat layer formed during drying.

Abstract: An electrophotographic apparatus in which toner particles are moved from the toner hopper or dispenser cartridge to the developer housing and onto the donor roller in a single component development system for use in color reprographic systems. A rotating holey tube toner agitator is modified to incorporate structure or grooves on the outer peripheral surface. Further, by placing a shrouded toner dispense auger inside the holey tube, the development system architecture stays compact and improved toner powder pushing through the pre-load of toner on the donor roller results, thereby insuring delivery of fresh toner evenly across the length of the developer housing. With more efficient pre- load, agitator rotational speed and bias can be reduced, leading to less toner effluents emanating from the developer housing without adversely affecting the cycle to cycle donor roller toner reload.
