Abstract

Sub-micron particles of a ferromagnetic or ferrimagnetic material may be dispersed in an optically clear matrix to produce a high transmittance, superpara-magnetic composite toner. The composite has a serviceable initial permeability and is suitable for color applications due to the low optical density of the magnetic toner.

Proposed Classification

Int. C1. G03g 9/00

Sub-micron particles of a ferromagnetic or ferrimagnetic material may be dispersed in an optically clear matrix to produce a high transmittance, superpara- magnetic composite toner. The composite has a serviceable initial permeability and is suitable for color applications due to the low optical density of the magnetic toner. The composite may be employed as a single developer component in magnetic development of electrostatic latent images.

Dyes or pigments may be included to produce any desired color.
