ABSTRACT:
Disclosed is a transfer-type one-component dry magnetic developer which comprises a binder medium having a high electric resistance and particles of triiron tetroxide of an isometric system having a particle size of 0.25 to 1 micron and a coercive force of 30 to 80 Oe, in which the triiron tetroxide particles are dispersed in the binder medium.
This developer provides a transferred image excellent in the density, sharpness and clarity on a plain paper as a transfer sheet in the electrostatic photography.
