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.

Developer recycling method

A toner recycling method and a toner recycling system use two personal computers and a display. A personal computer carries out management of information of toner, which is collected at a toner collection site. Another personal computer generates recycling information, which includes information about toner requirement of a granule manufacturer. A display at the toner collection site displays recycling information. Collected toner is used for manufacturing flux by mixing with aluminum dross, aluminum ash, aluminum dregs etc.
