<p>PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner excellent in fixing characteristics such as the peelability of a fixing sheet, the adhesion and bending resistance of a fixed image, the dispersibility of a releasing agent in the toner and OHP transparency and capable of giving a fixed image having high image quality, and provide its production method, a developer and an image forming method. SOLUTION: Relating to the electrostatic charge image developing toner contg. a colorant, a bonding resin and a releasing agent, relaxation modulus G(t) in relaxation time t=10×Dt (Dt: heating time in fixation) obtd. by the measurement of kinematic viscoelasticity is within the range of 2.0×102 to 3.0×103 Pa or relaxation modulus G(t=0.01) in 0.01 sec relaxation time is in the range of 2.0×102 to 3.0×104 Pa and the ratio [G(t=0.01)/G(t=0.1)] of the relaxation modulus G(t=0.01) to relaxation modulus G(t=0.1) in 0.1 sec relaxation time is in the range of 1.0 to 18.0.</p> |
