Toner

A toner having toner particles, each of which contains a binder resin and a wax, wherein,

• the toner is obtained by attaching a metal compound to the toner particles' surface and thereafter performing a surface treatment with a hot air current,
• the binder resin contains a polyester resin,
• the metal compound is formed by coordinating or bonding an aromatic oxycarboxylic acid represented by general formula (1) to a metal:
• where,
• R1 represents a quaternary carbon, methine, or methylene, each of which may contain N, S, O, or P atom, Y represents a cyclic structure bonded by a saturated bond or an unsaturated bond, and R2 and R3 each independently represent an alkyl group, aryl group, aralkyl group, cycloalkyl group, alkenyl group, alkoxyl group, aryloxy group, hydroxyl group, acyloxy group, alkoxycarbonyl group, aryloxycarbonyl group, acyl group, carboxyl group, halogen, nitro group, amino group, or carbamoyl group, wherein these may be substituted by a substituent;
• r is 0 or an integer from 3 to 12, o is 0 or an integer from 1 to 8, p is 0 or an integer from 1 to 4, and q is 0 or an integer from 1 to 3, and
• the binder resin is crosslinked with itself via a metal in the metal compound on the toner particles' surface.
