Document Type and Number:
Japanese Patent JP2010060895
Kind Code:
A
Abstract:
To provide an electrostatic charge developing toner capable of suppressing deterioration of fluidity, at the same time, suppressing breakage and deformation of toner and reducing bleed-out of a specified magenta pigment (C.I. pigment-red 57:1) to toner surface.
The electrostatic charge developing toner includes: a binder resin; and C.I. pigment-red 57:1 as a colorant, wherein a volume average particle size (D50v) of toner is 6 m to 9 m, a volume average particle size distribution index (GSDv) of toner is 1.35 or more and is less than 1.5 and a shape factor (SF1) of toner is 110 to 140.
