<p>PROBLEM TO BE SOLVED: To provide a toner resin composite and toner excellent low temperature fixability, offset resistance and blocking resistance, particularly excellent in low temperature fixability, and having wide fixing temperature range, and capable of providing a stable image of high quality. SOLUTION: This composite is obtained by graft-bonding a low melting point material (b) having a melting point of 50-120 deg.C to a vinyl polymer (a) mainly composed of a low molecular weight vinyl polymer component having a maximum molecular weight distribution in the molecular weight area of 3×10<3> -5×10<4> , and a high molecular weight vinyl polymer component having a maximum molecular weight distribution in the molecular weight area of 3×10<5> -5×10<6> . The low melting point material (b) is graft-bonded to the high molecular weight vinyl component of the vinyl polymer (a) more than to the low molecular weight vinyl polymer component thereof.</p> |
