PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development that is excellent in color reproducibility of PANTONE 7597C.SOLUTION: There is provided a toner for electrostatic charge image development that includes toner particles containing at least a binder resin, C.I.PigmentYellow 74 as a yellow colorant, and at least one red colorant selected from the group consisting of C.I.PigmentRed 48:1, C.I.PigmentRed 48:3, C.I.PigmentRed 57:1, and C.I.PigmentRed 184, where when an image in which a toner mounting amount T (g/m) satisfies the formula T=4×D/7, wherein D represents a value obtained by subtracting a unit of length from a volume average particle diameter (μm) of the toner particles, is formed on coat paper having a glossiness of 40%, the color difference E from PANTONE 7597C is within 10. 【課題】ＰＡＮＴＯＮＥ７５９７Ｃの色再現性に優れた静電荷像現像用トナーの提供。【解決手段】少なくとも結着樹脂と、黄色着色剤としてＣ．Ｉ．ＰｉｇｍｅｎｔＹｅｌｌｏｗ７４と、Ｃ．Ｉ．ＰｉｇｍｅｎｔＲｅｄ４８：１、Ｃ．Ｉ．ＰｉｇｍｅｎｔＲｅｄ４８：３、Ｃ．Ｉ．ＰｉｇｍｅｎｔＲｅｄ５７：１、及びＣ．Ｉ．ＰｉｇｍｅｎｔＲｅｄ１８４からなる群より選択される少なくとも１種の赤色着色剤と、を含有するトナー粒子を含み、光沢度が４０％のコート紙に、トナー載り量Ｔ（ｇ／ｍ２）が「Ｔ＝４?Ｄ／７（但し前記Ｄは前記トナー粒子の体積平均粒径（μｍ）から長さの単位を除いた値を示す）」の式を満たす画像を形成した際における、ＰＡＮＴＯＮＥ７５９７Ｃとの色差 Ｅが１０以内である静電荷像現像用トナー。【選択図】なし
