In a Non-magnetic Mono-component Process, High durability toner for Longer Life Cartridges is expected especially for higher printing speed. The key factor for long life is the high durability toner and it can be measured by the level of contamination onto the charging blade/developer roller. A toner was developed with this feature and the improvement carried out by utilizing a Cyclo Olefin Copolymer resin. The toner durability was examined by comparing on the charging blade/developer roller contamination with typical toner binders such as styrene/acrylic and polyester resins.
