(57) [Summary] [PROBLEMS] To improve low-temperature fixability and offset resistance, to form a high-quality toner image, and to have stable charging performance without fog even in long-term durable use. An object of the present invention is to provide a toner having excellent storage stability. SOLUTION: The toner containing at least a binder resin, a coloring agent and an organometallic compound, wherein the organometallic compound is capable of binding to an iron atom and a substituent selected from at least one alkyl group and a carbamoyl group. An azo iron compound that can be produced from a monoazo compound having two hydroxyl groups, wherein the binder resin has at least (i) an acid value of 1 a mixture of a vinyl resin having an acrylic acid or methacrylic acid unit and a vinyl resin having a glycidyl group in an amount of more than 100 mgKOH / g and less than 100 mgKOH / g, (ii) A vinyl resin having an acid value of more than 1 mgKOH / g and less than 100 mgKOH / g and an acrylic acid or methacrylic acid unit and a glycidyl group, and (iii) a vinyl resin obtained by reacting an acrylic acid or methacrylic acid unit with a glycidyl group. It is characterized by containing one or more members selected. |
