ABSTRACT:
An electrostatic image is developed by disposing an electrostatic image bearing member which holds an electrostatic image on its surface and a developer carrying member which carries an insulating developer on its surface with a certain gap provided therebetween, at a developing section bringing an insulating developer containing a nitrogen-containing compound to a thickness thinner than the gap on the developer carrying member and transferring said developer onto the above electrostatic image bearing member at the developing section. The nitrogen-containing compound has nitrogen in the form of a heterocyclic ring and imparts stable positive chargeability to the developer.
