Summary:PROBLEM TO BE SOLVED: To provide electrostatic charge image developing magenta toner, developer, an image forming method and an image forming apparatus having excellent color reproducibility and light resistance, and capable of suppressing generation of a color deviation and a decline of transfer efficiency.SOLUTION: The electrostatic charge image developing magenta toner contains resin and colorant. The magenta toner contains C.I. Pigment Red 48-3 and C.I. Pigment Red 48-1 in a weight ratio of (8:2) to (5:5) as a colorant. A time constant of the electrostatic charge image developing magenta toner is 1100-1300 m/sec.
