Patent ID: 8518623

Claim:
A toner comprising a toner particle that comprises: a binding resin; a colorant; a polar resin H; and a polar resin L, wherein the toner particle is obtained with granulation in a water-based medium, and the polar resin H and the polar resin L are each a polar resin containing a carboxyl group and having an acid value of 3.0 (mgKOH/g) or more, wherein when an SP value of the binding resin is denoted by δB ((cal/cm 3 ) 1/2 ), an SP value of the polar resin H is denoted by δH ((cal/cm 3 ) 1/2 ), and an SP value of the polar resin L is denoted by δL ((cal/cm 3 ) 1/2 ), the following formulas are satisfied; 8.70≦δ B≦ 9.50 1.00≦δ H−δB≦ 3.00 |δ L−δB|≦ 0.70, wherein when a glass transition point of the polar resin H is denoted by TgH (° C.) and a glass transition point of the polar resin L is denoted by TgL (° C.), the following formulas are satisfied; 65.0≦ TgH≦ 85.0 75.0≦ TgL≦ 105.0 TgH<TgL, wherein when a weight-average molecular weight of the polar resin H is denoted by MwH and a weight-average molecular weight of the polar resin L is denoted by MwL, MwH is 5.0×10 3 or more and 1.5×10 4 or less, and MwL is 1.0×10 4 or more and 3.0×10 4 or less, wherein a content of the polar resin H with respect to 100.0 parts by mass of the binding resin is 1.0 part by mass or more and 10.0 parts by mass or less, and a content of the polar resin L with respect to 100.0 parts by mass of the binding resin is 5.0 parts by mass or more and 25.0 parts by mass or less, wherein δH is 10.00 or more and 12.00 or less, and wherein δL is 8.80 or more and 10.00 or less.
