A non magnetic toner comprises toner particles each containing at least a binder resin, a colorant and a wax component. The toner further comprises an inorganic fine powder. A storage elastic modulus at 110° C. (G′110) of the non magnetic toner is in a range of 2.00×104 to 2.00×105 dN / m2. A storage elastic modulus at 150° C. (G′150) of the non magnetic toner is in a range of 3.00×103 to 2.00×104 dN / m2. The toner particles are obtained by dispersing a polymerizable monomer composition containing polymerizable monomers, the colorant, the wax component and a low-molecular weight polymer into an aqueous medium, granulating the dispersed polymerizable monomer composition, and polymerizing the polymerizable monomers in granulated particles. The low-molecular weight polymer has a weight average molecular weight (Mw) measured by means of gel permeation chromatography (GPC) in a range of 2000 to 5000.

The invention discloses a face mask capable of preventing fogging of glasses. According to the technical scheme, the face mask is characterized in that by forming an independent inhaled air and exhaled air flowing channel, and the exhaled air flows out along the designed channel and cannot flow to the upper portion of the nose, so that fogging of the glasses is avoided. In order to solve the problem that the inhalation resistance is increased due to the design of the independent flowing channel, a special respiration assisting device is arranged, the respiration assisting device comprises a chamber, an elastic air bag is arranged in the chamber and connected with an exhalation pipe, the chamber is connected with an inhalation pipe, the exhalation pipe is connected with an exhalation pipe control device, and accordingly, when exhalation is conducted through the exhalation pipe, because the air bag becomes large, the air in the chamber can be discharged into the inhalation pipe for inhalation of people. When one time of exhalation is completed, the exhalation pipe control device discharges the air in the air bag, because the air bag becomes small, the outside air enters the chamber due to air pressure difference, so that the aim of assisting the respiration is achieved. By means of the face mask, fogging of the glasses can be avoided to the greatest extent, and the respiration assisting function is achieved.
