摘要

The invention relates to binder type carrier comprising at least magnetic particles and binder resin having an acid value of 50 mg KOH/g or less and a hydroxyl value of 50 mg KOH/g or less, in which a product of the acid value by the hydroxyl value is within the range of from 1 to 600, which gives a high specific volume resistance of equal or more than 1013 OMEGA cm, and an excellent humidity resistance.
