摘要

PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development which can be fixed in a low-temperature region and can suppress gloss unevenness of an image even when fixed in a medium-to high-temperature region.

SOLUTION: The toner for electrostatic charge image development has toner base particles containing a crystalline resin, a release agent and a metal element capable of taking a valence of ≥2, wherein an intensity ratio of the metal element capable of taking a valence of ≥2 to intensity of all elements in the toner base particles is in a range of 5-50% as measured by fluorescent X-ray analysis.
