Abstract
In a method for recycling a double component developer that contains a carrier and a toner used for an image forming device such as office automation equipment, an economic value of recycling is increased, thereby allowing a company to carry out an active and sustainable environmental activity. Material components of a carrier are completely utilized, so that a process of removing and disposing part of components of the carrier, which is present in the conventional technology of a carrier recycling, is omitted from a recycling system, and in consequence, a cost of recycling is minimized. Furthermore, as well as a subject of the recycling, i.e. a carrier itself, a more valuable material, i.e. a platinum group metal, is utilized for the recycling.
