<p>PURPOSE:To provide a magnetic developer able to obtain highly accurate image, easily removable from the surface of an image carrier after transferring and excellent in cleaning property. CONSTITUTION:In the magnetic developer made by mixing a magnetic carrier with a magnetic toner containing at least a binding resin, a magnetic powder and a charge controlling agent in the weight ratio of (90:10)-(10:90), the magnetic toner is formed by burying the powder of a magnetic body having 0.01-3mum preferably 0.1-1mum average particle diameter into the particle of the toner produced by the polymerization method and having 2-9mum average particle diameter.</p> |
