ABSTRACT:
An electrostatic-image developer which comprises: (i) a toner comprising: (a) toner particles containing carbon black in an amount of from 6 to 8% by weight based on the weight of the toner particles and having a volume-average particle diameter of from 3 to 9 .mu.m; and (b) an external additive; and (ii) a resin-coated carrier having a volume resistivity of from 10.sup.7 to 10.sup.11 .OMEGA..multidot.cm in an electric field of 10.sup.3.8 V/cm and an average particle diameter of from 30 to 60 .mu.m. Also disclosed are a process for forming a black image and a process for forming a full-color image each using the electrostatic-image developer.
