<p>PROBLEM TO BE SOLVED: To provide a toner for developing an electrostatic charge image adaptable to a high speed machine provided with an oilless fixing mechanism and superior in its non visual offsetting ability. SOLUTION: In the toner for developing the electrostatic charge image containing at least resin, colorant and crystalline substance, the toner is provided with an endothermic peak between 60 to 100 deg.C in a DSC curve, the endothermic quantity is 4 to 30 J/g and the toner particles are provided with an island structure. In this case, among the toner for electrostatic charge developing, the number of islands whose average value of the distance between closest walls is 100 to 1,060 nm and the number of islands whose distance between the closest walls is >=1,300 nm are <=10% of the whole number of islands in the toner.</p> |
