Toner using small-particle size magnetic iron oxide

摘要

Provided is a magnetic toner which exhibits a high degree of blackness and high tinting strength, and in which scraping of a toner carrying member surface by the magnetic toner is not caused, and image defects such as fogging and tailing are suppressed. A magnetic toner comprising a magnetic toner particle that contains a binder resin and a magnetic iron oxide particle, wherein, the number-average particle diameter of the magnetic iron oxide particle ranges from 0.05 µm to 0.15 µm, and a relationship between the number-average particle diameter (µm) of the magnetic iron oxide particle and the specific surface area (m 2 /g) of the magnetic iron oxide particle satisfies Expression (1) below.
