Claim:
1. An electrostatic charge image developing toner comprising: toner particles; crosslinked resin particles having a glass transition temperature of 55° C. or higher, which are entirely disposed inside of the toner particles and are present within a surface layer of the toner particles, the surface layer being defined as a section of a toner particle that extends a depth of 300 nm from an outer surface of the toner particle; and silica particles disposed on the surface of the toner particles, the silica particles having a volume average particle diameter of 30 nm to 300 nm and a coverage with respect to the toner particle from 50% to 100%, wherein an area ratio of an area of the crosslinked resin particles and an area excluding the area of the crosslinked resin particles (area of the crosslinked resin particles/area excluding the area of the crosslinked resin particles) in a cross section of the surface layer portion is from 0.1 to 0.5, and the crosslinked resin particles are selected from a styrene crosslinked polymer, a (meth)acrylic crosslinked polymer, and a styrene-(meth)acrylic crosslinked polymer.
