A method of decreasing the light-off time of a catalytic exhaust aftertreatment device, using exhaust gas recirculation in a turbocharged internal combustion engine. The planetary gear mechanism includes a carrier to which rotation of the spool is transmitted, a planetary gear rotatably supported by the carrier and an internal gear for meshing with the planetary gear and actuating the operation member. A maximum partition portion is formed between a trailing end side of an intake port and a leading end side of a discharge port in a rotor chamber of the pump body. There is further disclosed a corresponding apparatus. The hybrid toner prevents a toner blocking phenomenon, image contamination, and low storage stability which occur due to dispersion of wax and colorants to an outer surface of the toner.
