摘要： An electrophotographic toner is formed of toner particles each comprising at least a binder resin, a colorant and a release agent, and a low-crystalline aromatic metal compound present at surfaces of the toner particles. The toner has an average circularity of at least 0.955, and the low-crystalline aromatic metal compound has an X-ray diffraction characteristic free from peaks exhibiting a measurement intensity of at least 10000 cps and a half-value half-width of at most 0.3 deg. in a range of measurement angles 2&thgr; of 6 to 40 deg. Because of the low crystallinity, the aromatic metal compound is uniformly applied onto the toner particle surfaces to stabilize the chargeability and transferability of the toner.

摘要： A magnetic toner has magnetic toner particles, each of the magnetic toner particles containing a binder resin and a magnetic material, and an inorganic fine powder. The magnetic material is prepared by treating the surface of magnetic iron oxide with a silane compound. When the magnetic iron oxide is dispersed in an aqueous solution of hydrochloric acid and dissolved until the dissolution proportion of the iron element reaches 5% by mass based on the total amount of the iron element contained in the magnetic iron oxide, the amount of silicon eluted by that point of time is 0.05% by mass or more and 0.50% by mass or less based on the magnetic iron oxide. The magnetic material has a moisture adsorption amount per unit area of 0.30 mg/m2 or less.
