摘要： The toner of the present invention is suitably used in SLIC development system where a liner velocity of a developer-bearing member is 150 to 500 cm/sec. The toner has resin particles containing at least a coloring agent, and a charge controlling agent fine articles, and a ratio M/T of the amount M (% by weight) of an element in the surface of toner particles as determined by X-ray photoelectron spectroscopy (XPS) to the amount T (% by weight) of the element in the entire toner particles of 20 to 500, which element is present only in a charge control agent among components of the toner and is an element belonging to one of the first, second, third, fourth, and fifth periods of the long form of periodic table of elements except hydrogen, carbon, oxygen, and rare gas elements.

摘要： A toner fixable on an image bearer with heat. The toner has a first storage modulus of from 1×103 to 1×106 Pa, measured at 100° C. when being heated, and a second storage modulus of from 1×103 to 1×106 Pa, measured at 100° C. when being cooled, the first storage modulus and second storage modulus being measured by a rheometer, and the second storage modulus at 100° C. when being cooled is higher than the first storage modulus at 100° C. when being heated.
