摘要 |
The invention disclosed concerns a method of forming dichromatic copy images. An electrostatic latent image having a first image portion and a second image portion is formed. The first image portion is developed by a first magnetic brush developing device using at least a magnetic toner of first color triboelectrically chargeable to a specific polarity. The second image portion is developed by a second magnetic brush developing device using a mixture of a magnetic carrier substantially not triboelectrically chargeable with the magnetic toner and a non-magnetic toner of a second color triboelectrically chargeable to a polarity opposite to that of the magnetic toner by contact with the magnetic carrier.
