<P>PROBLEM TO BE SOLVED: To provide a two-component developer that has excellent flowability, stably charges toner, and stably forms a high-definition image over a long period of time. <P>SOLUTION: The two-component developer includes a toner 3 containing a binder resin, a colorant, and a release agent, and a resin-coated carrier 2 comprising a carrier core material 2a and a resin coating layer 2b formed on a surface of the carrier core material 2a. The toner 3 has an exposure rate of the release agent on the toner 3 surface of 1.00-3.07%. The carrier core material 2a has an apparent density of 1.86-2.45 g/cm<SP>3</SP>. The exposure rate of the release agent of the toner 3 and the apparent density of the carrier core material 2a satisfy the following formula (1) y≤-1.54x+5.93, wherein y represents the exposure rate of the release agent of the toner 3, and x represents the apparent density of the carrier core material 2a. <P>COPYRIGHT: (C)2011,JPO&INPIT |
