摘要： This invention relates to image formation toner, 2-component developer, image formation method and method for manufacturing image formation toner, for preventing clogging of the filter. Toner is used in which the ratio of the component measured by GPC to have a molecular weight between 500 to 1000 is 10 parts by weight or less with respect to 100 parts by weight of the entire toner. Since the case of clogging of the HEPA filter is the 500 to 1000 molecular weight component, clogging of the filter is prevented by reducing this component.

摘要： An electrophotographic toner comprising a binder resin and a colorant, which is used in electrophotographic process employing a flash fixing system for fixation of a transferred toner image, wherein the binder resin is a polyester resin which partially contains a chloroform-insoluble content; and the toner contains a polypropylene resin and an ester type structure resin represented by the following formula (I); wherein p, q, m and n each represents a positive integer of 16 to 22 and R may be the same or different and each represents a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms. The electrophotographic toner is capable of remarkably enhancing the fixation strength of the toner and inhibiting the occurrence of voids during the printing and the occurrence of fuming and odor during the fixation.
