摘要:
[Summary] An object of the present invention is to provide a toner that has both low-temperature fixability and heat-resistant storage stability, suppresses contamination of cleaning parts and photoconductors, and has excellent charging stability.
[Tasks] A toner includes toner based particles containing a binder resin, a colorant, and a wax; and fine resin particles and an inorganic external additive that are present on a surface of the toner based particles, wherein a coverage of the fine resin particles is in a range from 30% to 70%, and wherein the inorganic external additive covers a surface of oxide of a metal element with hydroxide of a metal element.
