摘要：
A toner for developing an electrostatic image, includes: colored particles containing a colorant and a binder resin, and two or more kinds of inorganic particles that are externally added to a surface of the colored particles, in which the two or more kinds of inorganic particles contain titanium-containing particles and silica-containing particles, an exposure ratio of the surface of the colored particles is about 25% or less, and a ratio of the titanium-containing particles that are in contact with the colored particles is about 15% by number or less.
