摘要:
A composition for developing electrostatic latent images in electrographic printing or copying machinery is provided in which a toner component is blended with 10 to 40% by weight of a carrier. The toner component includes magnetic toner particles each having magnetic powder bound in a resin, and magnetic particles in admixture with the magnetic toner particles, preferably as an external additive in an amount of 0.1 to 10% by weight.

摘要:
A ferrite powder type magnetic toner used in an electrophotography. It comprises a resinous component and a ferrite having a spinel structure comprising components of iron oxide at a ratio of 99.9 to 51 mole% as Fe 2 0 3 and at least one metal oxide selected from the group consisting of manganese oxide, nickel oxide, cobalt oxide, magnesium oxide, copper oxide, zinc oxide and cadmium oxide at a ratio of 0.1 to 49 mole% as MO wherein M represents Ni, Co, Mg, Cu, Zn or Cd. A process for producing the ferrite component of said toner, involving the steps of mixing, granulating, sintering and pulverizing, is described.
