Date Oct. 15, 1981.This is one-component type dry developer for an electrophotography which is improved on humidification ability, and consists of mixture of toner with a particle size of 5 DIFFERENCE 50 ( mu ) and hydrophobic flow agent. The flow agent is made by covering inorganic, organic, metallic or alloy powder with thin film of non-hydrophilic synthetic resin. By using electric conductive material as core and making a range of resin film thickness so as to cause tunnel effect of electron or ion, the flow agent which has non-hydrophilic property and electric conductive property is obtained.</p> |
