    摘要： A magnetic material is provided that has an iron oxide phase whose principal phase is a crystal of a structure which has the same space group as ε-Fe2O3 crystal and in which Al is substituted for a portion of the Fe sites of the ε-Fe2O3 crystal. The molar ratio of Al to Fe in the iron oxide phase, when expressed as Al:Fe=x:(2−x), satisfies 0≦x≦1. The value of x is preferably in the range of 0.3 to 0.7. The average particle diameter of the powder determined from a TEM image is preferably 5 to 200 nm, more preferably 10 to 100 nm. The magnetic material has very high practical value because it enables the extremely high coercive force Hc of the ε-Fe2O3 crystal to be regulated to a level enabling utilization in magnetic recording medium and various other applications. The magnetic powder can be produced by a method combining the reverse micelle method and the sol-gel method.

    摘要： The invention provides a toner that is capable of low-temperature fixing even in high-speed electrophotographic processes while keeping the cleaning performance when used at high temperatures and the high-temperature storage stability. This toner having toner particles, each of which contains a binder resin and a colorant is characterized in that the temperature of Tp [° C.] when the loss elastic modulus obtained by dynamic viscoelastic measurements on the toner exhibits a maximum value in the temperature range from at least 30° C. to not more than 200° C., is from at least 40° C. to not more than 55° C., and in that, with G″(Tp) [Pa] being this maximum value, G″(Tp+15) [Pa] being the loss elastic modulus at the temperature of Tp+15 [° C.], and G″(Tp+30) [Pa] being the loss elastic modulus at the temperature of Tp+30 [° C.], G″(Tp), G″(Tp+15), and G″(Tp+30) satisfy prescribed relationships.
