ABSTRACT:
A toner for image formation is provided, which is produced by dispersing in an aqueous solvent a toner composition which includes a composition thermally soluble in an organic solvent and a coloring agent, thereby forming toner particles, wherein the thermally soluble composition includes (a) a polyester having an acid value and (b) a metal alcolate and/a metal chelate compound. The toner is capable of attaining image fixing at a sufficiently low image fixing temperature and a sufficiently broad image fixing temperature range for use in practice. Furthermore, toner containers such as a toner cartridge and a process cartridge are provided, which are loaded with the toner. Such toner containers can be detachably mounted on an image forming apparatus.
