<p>PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development excellent in a low temperature fixing property and an offset resistant property and with less lowering of picture image density. SOLUTION: The maximal endothermic peak P1 in a temperature region exists at 60 deg.C-90 deg.C, the maximal endothermic peak P2 in the temperature region exists at 50 deg.C-150 deg.C, a difference between peak temperature of the maximal endothermic peak P1 and peak temperature of the maximal endothermic peak P2 is more than 15 deg.C and an electric charge controller is an imidazole derivative shown in an expression (R1 , R2 , R3 , R4 are a hydrogen atom, an alkyl group, an aryl group and an aralkyl group, and they are right to be the same or different from each other).</p> |
