ABSTRACT:
To provide a toner for developing an electrostatic charge image, which has a good low temperature fixing property whereby it is useful for an image-forming device of a low temperature heat fixing system using a heat roll having a surface temperature of at most 150° C. and it does not fuse to a blade or a toner transport roller, and which is excellent in durability with little change in the image quality in a continuous copying operation.A toner for developing an electrostatic charge image, having base toner particles comprising at least a binder resin and a coloring agent, wherein the base toner particles contain an oil having a surface tension of at most 30 mN/m at 25° C., and the toner has a softening point of at most 100° C.
