<p>PROBLEM TO BE SOLVED: To provide a dry toner which always exhibits good eleotrostatic charge characteristics independently of a change of the service environment such as high temperature and high humidity or low temperature and low humidity, gives a stable image even after many images are formed over a long period of time and is excellent in durability and matchability with an image forming device. SOLUTION: The dry toner has at least toner particles and inorganic fine particles treated with at least (i) a silicone oil, (ii) a silylating agent and/or a silane coupling agent and (iii) a silanol compound. The silanol compound content of the inorganic fine particles is 15-1,000 ppm.</p> |
