PROBLEM TO BE SOLVED: To provide toner for forming a stable image over a long time while preventing image density from varying with humidity, even when manufactured by coagulating resin particles and a coloring agent in a water-medium. SOLUTION: This toner contains silica particles treated by using silicone oil whose kinetic viscosity is 10 to 10,000 mm<SP>2</SP>/s at 25°C on the surfaces of colored particles manufactured by coagulating at least resin particles and coloring agent particles in a water-medium.
