Abstract
Toner particles contained in a liquid developer 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. The second resin satisfies Equations (1) to (2) below. In Equations (1) to (2) below, x represents a number average molecular weight of the second resin and y represents a urethane group concentration (mass %) in the second resin.−0.00003+2.03≦≦−0.00003+6.95  Equation (1)10000≦≦50000  Equation (2)
