摘要: This invention relates to a toner for developing an electrostatically charged image of a heat roller type copier or printer, the toner consisting essentially of a binder resin, a colorant and a charge control agent, in which the binder resin at least includes a polyolefin resin having a cyclic structure, and a polyolefin resin of a cyclic structure having an intrinsic viscosity (i.v.) of 0.25 dl/g or more, a heat distortion temperature (HDT) by DIN53461-B of 70° C. or higher, and a number average molecular weight of 7,500 or more and a weight average molecular weight of 15,000 or more, as measured by GPC, is contained in a proportion of less than 50% by weight based on the entire binder resin. The toner for developing an electrostatically charged image according to the invention is excellent in fixability, light transmission, and anti-toner spent properties, giving a sharp, high quality image, can be applied to any of a dry one-component magnetic toner, a dry one-component nonmagnetic toner, a dry two-component toner and a liquid toner, and exhibits marked effects particularly when used in a color toner.

摘要: This invention relates to a toner for electrophotography which develops an electrostatically charged image, the toner at least containing a coloring agent, a binder resin, a charge control agent, and a functioning agent, wherein low molecular weight polyolefin wax obtained by a metallocene type polymerization catalyst is contained as the function imparting agent. The toner of the invention is excellent in fixability, and has offset preventing properties, heat response characteristic, anti-spent toner properties, and storage stability, which can thus obtain a sharp, high quality image.
