Patent ID: 7157198

Claim:
Toner for electrostatic latent image development comprising at least a resin, a coloring agent and a crystalline compound wherein; toner particles have a sea-island structure, in which a mean value of distances between most proximal walls between islands of the crystalline compound is from 100 to 1060 nm, and percentage of the islands of the crystalline compound in which the distance between the most proximal walls is 1300 nm or more is 10% or less by number in the total islands of the crystalline compound; the crystalline compound comprises 92% or more by mass of n (normal)-paraffin, and a plurality of types of n-paraffin components with different numbers of carbons, and a peak top temperature of a largest endothermic peak is from 70 to 120° C. in an endothermic curve measured by DSC, a peak width at half height of the largest endothermic peak is 12° C. or less, and a penetration is 4 or less; and wherein 98% or more of the toner particles have no island which is exposed on the toner particle surface.
