摘要

PROBLEM TO BE SOLVED: To provide a two-component developer having high low-temperature fixability of toner and high carrier resistance. A two-component developer 10 according to the present invention includes a carrier 20 and a toner 30. Here, the coating resin, which is the main material of the coating agent 24 of the carrier 20, is composed of a silicone resin and an acrylic resin. The toner 30 contains a crystalline polyester resin in addition to the main resin as its main material. Further, the difference between the SP value of the coating resin of the carrier 20 and the SP value of the main resin of the toner 30 is 1.5 or more. At the same time, the SP value of the crystalline polyester resin contained in the toner 30 is set to 9.0 or more, preferably 10.5 or less. As a result, the two-component developer 10 having high low-temperature fixability of the toner 30, high spint resistance of the carrier 20, and high storage stability is realized.
