Abstract
Toner particles have a core-shell structure that first resin particles containing a first resin are attached to or cover surfaces of second resin particles containing a second resin. Heat of fusion with differential scanning calorimetry of the second resin satisfies Equations (1) to (2) below. In Equations (1) to (2) below, H1 and H2 represent heats of fusion (J/g) at initial temperature increase and second temperature increase with differential scanning calorimetry of the second resin, respectively.5≦1≦70  Equation (1)0.2≦2/1≦1.0  Equation (2)
