Patent ID: 8685603

Claim:
An electrostatic charge image developer, comprising: a toner containing an external additive; and a carrier comprising a resin-coated layer formed on a surface of a core material, wherein a resin that forms the resin-coated layer contains a copolymer of a monomer containing (i) a cycloalkyl group and (ii) a styrene monomer or dimethylamino methacrylate, an average shape factor SF1 of the toner being from about 125 to about 135, a number of particles having a shape factor SF1 of less than 125 being from about 5% to about 30% by number with respect to a total number of toner particles, a number of particles having a shape factor SF1 of greater than 135 being from about 5% to about 30% by number with respect to the total number of toner particles, a scratch line width in a scratch strength test of the resin used in the resin-coated layer being from about 80 Î¼m to about 200 Î¼m, and a scratch depth being from about 60 Î¼m to about 150 Î¼m.
