A toner having a crystalline resin added, which exhibits sufficient low-temperature fixability even during high-speed fixing, and has sufficient durability even in a development system in which the toner is loaded. A toner containing toner particles obtained by granulating and polymerizing a polymerizable monomer composition containing a polymerizable monomer, a colorant, a polar resin, and a crystalline resin in an aqueous medium. The polymerizable monomer, the polar resin, and the crystalline resin are specific, and the mass ratio of the crystalline polyester portion and the amorphous vinyl portion of the crystalline resin is in a specific range, When the melting point of the crystalline resin is Tm (C) (° C.) and the glass transition temperature of the polar resin is Tg (H) (° C.), the specific relationship is satisfied, and the acid value of the crystalline resin is Av ( C) (mgKOH / g), a toner satisfying a specific relationship when the acid value of the polar resin is Av (H) (mgKOH / g).
