MAGNETIC TONER

摘要

PURPOSE:To provide stable running characteristics and to obtain good images by mixing a mixture of at least two kinds of carbon black of which the difference in the oil absorption is >=15ml/100g as a conductive material. CONSTITUTION:A magnetic material, binder resin and conductive material are used as essential components for a magnetic toner. The conductive material consists of a mixture of at least 2 kinds of carbon black, of which the difference in the oil absorption is >=15ml/100g. The difference between the softening point and softening initiating temp. of the toner is made >=5 deg.C.
