摘要:
A toner comprising a binder resin and a wax, wherein the binder resin contains a binder resin A and a binder resin B, the binder resin A has a softening point of at least 120°C and not more than 150°C, has a polyester unit, and has a terminal of which a first aliphatic compound having a melting point of 60°C or more and not more than 85°C has been condensed, and the binder resin B has a softening point of at least 80°C and not more than 115°C, has a polyester unit, and has a terminal of which a second aliphatic compound having a melting point of 90°C or more and not more than 120°C has been condensed.
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.
