<P>PROBLEM TO BE SOLVED: To provide toner, improving high-temperature offset resistance without impairing low-temperature fixability, and restraining the occurrence of high-temperature offset even with a thin fixing roller. Ž<P>SOLUTION: Toner contains at least binder resin, a coloring agent and wax. The binder resin contained in this toner contains crosslinked styrene acrylic resin. The crosslinked styrene acrylic resin includes carboxyl group contained styrene acrylic resin, glycidyl group contained styrene acrylic resin and crosslinked component obtained by crosslinking the carboxyl group contained styrene acrylic resin and the glycidyl group contained styrene acrylic resin. The crosslinked component ranges from 5 wt.% to 40 wt.% of the whole quantity of the binder resin. The acid number of crosslinked styrene acrylic resin ranges from 3 KOH mg/g to 25 KOH mg/g. Wax contains polyolefin wax and ester-base wax. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
