Abstract:
A toner for forming an electrophotographic image comprising a toner particle comprising a resin and a colorant, wherein the toner particle comprises at least two inorganic salts including an inorganic salt comprising a positive ion having a first valence and an inorganic salt comprising a positive ion having a second valence different from the first valence, a total amount of the inorganic salt having the first valence is greatest among the inorganic salts in the toner particle, and a total amount of the inorganic salt having the second valence is second greatest among the inorganic salts in the toner particle, with the formulas of;2.0&gE;a&gE;0.1 1.0&gE;b&gE;0.01 7.5&gE;a/b&gE;1.1 wherein â€œaâ€  is percent by weight of the first inorganic salt based on the total weight of the toner and â€œbâ€  percent by weight of the second inorganic salt based on the total weight of the toner, and â€œaâ€  and â€œbâ€  is value in terms of anhydride.
