PROBLEM TO BE SOLVED: To provide a toner with which a high-quality image can be obtained even if printing is performed using an image forming apparatus in a low temperature and low humidity environment after the apparatus used over a long period of time is allowed to stand for several days under high temperature and high humidity conditions. SOLUTION: The toner comprises toner particles and inorganic fine powder, wherein the toner particles are formed in an aqueous medium, the toner particles of which the circle-equivalent diameter is 1.98-19.92μm have an average circularity of 0.970-1.000 and a standard deviation of the circularity of≤0.070, the inorganic fine powder of which the circle-equivalent diameter is 0.80-1.98μm has an average circularity of 0.960-1.000 and a standard deviation of the circularity of≤0.070, and the inorganic fine powder has an average pore diameter of 5.0-50.0 nm and a median diameter on a volume basis of 0.70-3.00μm.
