<p><P>PROBLEM TO BE SOLVED: To provide a magnetic toner excellent in low-temperature fixability and durability. <P>SOLUTION: The toner comprises: magnetic toner particles obtained by dispersing in an aqueous medium a dissolved material or dispersed material obtained by dissolving or dispersing a polyester-based resin, a magnetic iron oxide and a wax in ethyl acetate and then removing the ethyl acetate; and inorganic fine particles. In a test for still standing the magnetic iron oxide after being dispersed in the ethyl acetate and evaluating a decrease rate of a precipitated volume, a ratio (A5/A0) of the precipitated volume (A5) to a liquid level volume (A0) 5 minutes after the standing is 50% or more and 85% or less. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
