摘要 PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development that suppresses failure in peeling thin paper during high-speed fixing and can reduce the amount of generation of powderly dust inside an image forming apparatus.SOLUTION: There is provided a toner for electrostatic charge image development including a binder resin, a colorant, and a mold release agent, and having a sea-island structure having a sea part including the binder resin and island parts including the mold release agent, where the net intensity of sodium measured through fluorescent X-ray analysis is 0.05 or more and 0.30 or less; the degree of maldistribution B of the island parts including the mold release agent is represented by the following formula (1): degree of maldistribution B=2d/D, where D represents the equivalent circle diameter (μm) of the toner in observation of the cross section of the toner, and d represents the distance (μm) from the center of gravity of the toner particle to the center of gravity of the island parts including the mold release agent in the observation of the cross section of the toner; the most frequent value of the distribution of the degree of maldistribution B is 0.80 or more and 0.98 or less; and the skewness of the distribution of the degree of maldistribution B is -1.00 or more and -0.50 or less.SELECTED DRAWING: None
