Red toner for electrostatic image development, developer for electrostatic image development, toner set for electrostatic image development, developer set for electrostatic image development and image forming apparatus

A developer set for electrostatic image development, comprising:

• a magenta developer, a yellow developer, and a red developer, respectively containing a magenta toner, a yellow toner and a red toner, and a carrier,
• each of the magenta, yellow and red toners containing a binder resin, a coloring agent and a release agent,
• wherein
• the developer set for electrostatic image development satisfies the following formulae:
• 0.3<ID<1.2
• 5°<A<35°
• 0.2<(ID/IDmy)<0.7
• A<Amy
• wherein
• ID represents an image density when a first image is formed on a recording material with a toner loaded amount of 4.0 g/m2 of the red toner;
• A represents a hue angle of the first image expressed by an L*a*b* color coordinate space, provided that a hue angle of 0° is on the a*+axis and a hue angle of 90° is on the b*+axis;
• IDmy represents an image density when a second image is formed by the magenta toner and the yellow toner on a recording material with a toner loaded amount of 4.0g/m2 for each of the magenta toner and the yellow toner;
• and
• Amy represents a hue angle of the second image expressed by the L*a*b* color coordinate space,
• the red toner comprises a red pigment selected from the group consisting of C.I. Pigment Red 150, C.I. Pigment Red 221, and C.I. Pigment Red 31;
• the magenta toner comprises a magenta pigment selected from the group consisting of C.I. Pigment Red 185, C.I. Pigment Red 238, C.I. Pigment Red 269, and C.I. Pigment Red 122;
• and
• the yellow toner comprises a yellow pigment selected from the group consisting of C.I. Pigment Yellow 74 and C.I. Pigment Yellow 185.
