Title:
トナーの製造方法およびトナー、二成分現像剤、現像装置、画像形成装置
Document Type and Number:
Japanese Patent JP4572249
Kind Code:
B2
Abstract:
A method for producing a toner, that can produce a low temperature fixable toner in a stable manner, a toner produced by the production method, a two-component developer using the toner, a developing device and an image forming apparatus are provided. The toner is produced using an aqueous dispersion obtained by dispersing a crystalline self-dispersion polyester resin having at least one carboxyl group and containing a compound represented by the following chemical formula (1) as an alcohol component in an aqueous medium. The aqueous dispersion, a colorant particle aqueous dispersion and a wax particle aqueous dispersion are mixed to aggregate, and a non-crystalline self-dispersion polyester resin particle aqueous dispersion is further added to perform aggregation. The liquid mixture containing the aggregates is heated and washed, thereby obtaining a toner: HO—CH2CH2CH2CH2nOH (1) wherein n is an integer of from 2 to 50.
