摘要

A carrier is provided including a core and a resin layer located overlying the core, wherein the carrier has a weight average particle diameter (Dw) of from 22 to 50 mum, a ratio (Dw/Dp) of the weight average particle diameter (Dw) to a number average particle diameter (Dp) of from 1 to 1.30, a shape factor SF-1 of from 100 to 120, and a shape factor SF-2 of from 100 to 120, and wherein the carrier comprises core particles satisfying the following relationship 0.52<(d/D)<1.0 in an amount of from 0 to 10,000 ppm by number: wherein D (mum) represents a diameter of a circle having the same area as that of a projected image of a core particle and d (mum) represents a diameter of a circle having the same area as that of a projected image of a maximum hollow present in the core particle.
