(G′(100° C.)) of the toner is from 1.0×103 to 1.0×106 Pa, and a storage elastic modulus at 160° C. (G′(160° C.)) of the toner is from 1.0×102 to 1.0×104 Pa. A ratio of loss elastic modulus to storage elastic modulus at 100° C. (tan δ(100° C.)) of the toner is greater than that at 130° C. (tan δ(130° C.)), and the tan δ(100° C.) and the tan δ(130° C.) are each within the range of from 1 to 2.

摘要： Dispersoids having metal-oxygen groups that are suitable for the production of metal oxide thin-films at a low temperature of 200° C. or below and for the production of homogeneous organic-inorganic hybrid materials. The dispersoid having metal-oxygen bonds may be obtained by mixing a metal compound having at least three hydrolyzable groups with at least 0.5 mole but less than 2 moles of water per mole of the metal compound in an organic solvent, in the absence of an acid, a base, and/or a dispersion stabilizer, and at a temperature at or below the temperature at which the metal compound begins to hydrolyze, then raising the temperature to at least the temperature at which hydrolysis begins.
