Toner

A toner comprising toner particles,

• wherein:
• each of the toner particles comprises a core-shell structure composed of a core and a shell phase formed on the core, the shell phase containing a resin A, and the core containing a binder resin, a colorant and a wax,
• wherein
• (i) in measurement of the resin A by a differential scanning calorimetry (DSC), a peak temperature TpA (° C.) of a maximum endothermic peak in a first temperature rise is at least 55° C. but not more than 80° C.;
• (ii) in measurement of a viscoelasticity of the resin A, a loss elastic modulus G″a (TpA-10) at a temperature TpA-10 (° C.) which is 10° C. lower than the TpA is at least 1×107 Pa but not more than 1×108 Pa;
• (iii) in measurement of the viscoelasticity of the resin A, when the loss elastic modulus at the TpA (° C.) is G″a (TpA) [Pa], the loss elastic modulus at a temperature TpA+10 (° C.) which is 10° C. higher than the TpA is G″a (TpA+10) [Pa], and the loss elastic modulus at a temperature TpA+25 (° C.) which is 25° C. higher than the TpA is G″a (TpA+25) [Pa], and
• in measurement of a viscoelasticity of the binder resin, when a loss elastic modulus at the TpA+10 (° C.) is G″b(TpA+10) [Pa] and the loss elastic modulus at the TpA+25 (° C.) is G″b(TpA+25) [Pa],
• G″a(TpA), G″a(TpA+10), G″a(TpA+25), G″b(TpA+10) and G″b(TpA+25) satisfy the conditions of the following formulas (1), (2), (3) and (4):
• 1.0≦{log(G″a(TpA))−log(G″a(TpA+10)}≦4.0 (1);
• 0.1≦{log(G″a(TpA+10))−log(G″a(TpA+25)}≦0.9 (2);
• −1.5≦{log(G″a(TpA+10))−log(G″b(TpA+10)}≦1.0 (3);
• and
• G″a(TpA+25)>G″b(TpA+25) (4).
