Zusammenfassung:PURPOSE:To obtain stable running characteristics and good images by using a mixture of at least two kinds of which the difference in the oil absorption is >=4ml/100g as a magnetic material. CONSTITUTION:A magnetic material, binder resin and conductive material are used as essential components for a magnetic toner. The magnetic material consists of a mixture of at least two kinds of magnetic material components, of which the difference in the oil absorption is >=4ml/100g, more preferably 10- 80ml/100g. The difference between the softening point and softening initiating point of the toner is made >=5 deg.C.
