Abstract
An electrostatic charge image development toner contains toner particles and layered-structure compound particles. The layered-structure compound particles have a crystallite diameter of 150 Å or more and 250 Å or less as calculated from a maximum peak width in a Cu Kα X-ray diffraction chart and have a number-average particle diameter Dn of 0.3 μm or more and 2.0 μm or less. The ratio Dn/Dv of a number-average particle diameter Dn of the layered-structure compound particles to a volume-average particle diameter Dv of the toner particles is 0.03 or more and 0.7 or less.
