Abstract
A noncontact cleanerless system toner cartridge that uses an injection charging roller and toner with conductive particles is remanufactured into a conventional toner cartridge. The injection charging roller is removed and replaced with a primary charge roller. A cleaning blade to remove the residual toner from the organic photoconductive drum is added along with a seal to form a toner waste hopper area. The toner with the conductive particles is replaced with toner having magnetic particles.
