Cleaning agent for toners, method for producing cleaning agent for toners, and toner composition

A cleaning agent for toners, which is a fatty acid divalent metal salt obtained by double decomposition between a fatty acid-alkali compound salt, which is obtained by reaction of a fatty acid containing 8 to 24 carbon atoms with a monovalent alkali compound, and a divalent metal salt,

• wherein the fatty acid divalent metal salt is in a form of particles,
• wherein the fatty acid divalent metal salt has a water activity value A of from 0.65 to 0.85 at 25° C., which is calculated by the following formula (1),

• where P is water vapor pressure (Pa) at 25° C. inside a closed container containing the fatty acid divalent metal salt, and P0 is vapor pressure (Pa) of water at 25° C., and
• wherein the fatty acid divalent metal salt has a number average value B of area envelopment degrees of from 0.910 to 0.990, each of which is defined as a ratio of a projected area to an area inside an envelope (the projected area/the area inside the envelope) for a projected image, and the area envelopment degrees are those of projected images of particles having an equivalent circle diameter in a range of from a cumulative 10% diameter to a cumulative 90% diameter on a volumetric basis in all of the particles of the fatty acid divalent metal salt.
