ABSTRACT:
A toner for electrostatic image development, comprising an organic pigment and a binding resin, andsatisfying the formula (I):in-line-formulae description="In-line Formulae" end="lead"?1−R/A≦0.014C (I),in-line-formulae description="In-line Formulae" end="tail"?wherein A represents an entire area of a graph (x-axis: wavelength of a visible radiation region (380 to 780 nm), y-axis: transmittance (0 to 100%)) showing a spectral transmittance curve of a supernatant fluid, the supernatant fluid being obtained by subjecting the toner to an extraction process, the extraction process using a supercritical fluid; R represents an area determined by a Rectangular method on the basis of a spectral transmittance curve in the graph; and C represents a concentration (wt %) of the organic pigment in the toner,the organic pigment having a particle diameter of 1/10 to ½ ( 1/10 to 4/7 when the organic pigment is an organic yellow pigment) of a maximum absorption wavelength of the organic pigment, andthe toner having a haze of 16 or less.
