Provided is a toner for image formation in which a charging member such as a carrier and a charging blade is not contaminated, charging ability is not lowered with time, and toner is not scattered. A toner material liquid (oil phase) in which a toner material containing at least a binder resin and / or a binder resin precursor and a release agent is dissolved or dispersed in an organic solvent is emulsified in an aqueous medium (aqueous phase). A toner having base particles formed by solvent removal after being dispersed, and including at least an ester bond and a bond unit other than the ester bond as the binder resin and / or binder resin precursor A polyester or a resin precursor capable of producing the modified polyester, and a crystalline polyester, and the release agent is a microcrystalline wax having specific characteristics, and the release agent has a base material in the base particle. A toner having a dispersed particle diameter of 0.06 μm or more and 1.50 μm or less. [Selection] Figure 1 |
