Abstract:
A two-component developer includes toner particles and carrier particles. The toner particles each include a toner mother particle and first resin particles. The carrier particles each include a carrier mother particle and second resin particles. An amount of the second resin particles is at least 0.010 parts by mass and no greater than 0.100 parts by mass relative to 100 parts by mass of the carrier mother particles. The first resin particles and the second resin particles have a number average primary particle diameter of at least 40 nm and no greater than 100 nm and a blocking rate (measurement temperature: 160° C.) of less than 30% by mass. A difference in blocking rate between the first resin particles and the second resin particles is no greater than 5% by mass, and a difference in number average primary particle diameter therebetween is no greater than 5 nm.

Claim (Index 1):
A two-component developer comprising a toner and a carrier, wherein\n the toner includes a plurality of toner particles each including a toner mother particle and a plurality of first resin particles attached to a surface of the toner mother particle, the carrier includes a plurality of carrier particles each including a carrier mother particle and a plurality of second resin particles attached to a surface of the carrier mother particle, an amount of the second resin particles is at least 0.010 parts by mass and no greater than 0.100 parts by mass relative to 100 parts by mass of the carrier mother particles, a blocking rate measured for the first resin particles and a blocking rate measured for the second resin particles are each less than 30% by mass, each of the blocking rates being measured using a mesh having a sieve opening of 75 \u03bcm after 5-minute pressure application under conditions of a temperature of 160\u00b0 C. and a pressure of 0.1 kgf/mm 2 , a difference in blocking rate between the first resin particles and the second resin particles is no greater than 5% by mass in terms of an absolute value, respective number average primary particle diameters of the first resin particles and the second resin particles are at least 40 nm and no greater than 100 nm, a difference in number average primary particle diameter between the first resin particles and the second resin particles is no greater than 5 nm in terms of an absolute value, and the first resin particles and the second resin particles contain resins of the same species as each other.
