Claim:
1. A toner comprising: a toner particle containing a binder resin and a colorant; an iron oxide particle; an inorganic fine particle “a” selected from the group consisting of a silica particle, a titanium oxide particle and an alumina particle; and an organic-inorganic composite fine particle, the organic-inorganic composite fine particle comprising a vinyl resin particle and inorganic fine particles “b” which are embedded in the vinyl resin particle, at least a part of said inorganic fine particles “b” being exposed at surface of the organic-inorganic composite fine particle, wherein the organic-inorganic composite fine particle has convexes derived from the inorganic fine particles, a coverage ratio A of the toner particle surface with the inorganic fine particle “a” is 45.0 to 70.0%, a ratio of a coverage ratio B to coverage ratio A is 0.50 to 0.85, when coverage ratio B (%) is a coverage ratio of the inorganic fine particle “a” adhered to the toner particle surface, a coverage ratio C of the surface of the organic-inorganic composite fine particle with the inorganic fine particles “b” is 20 to 70%, and the content of the iron oxide particle present on a surface of the toner particle is 0.1 to 5.0% by mass based on the mass of the toner particle.
