ABSTRACT:
The present invention provides a mono-component developer comprising toner particles containing a binding resin, a colorant and an additive and a method of forming images by use thereof. In the present invention said additive is preferably a titanium compound prepared by through the reaction between TiO(OH).sub.2 and a silane compound or through the reaction between TiO(OH).sub.2 and a silicone oil. The specific gravity of the said titanium compound is in the range of 2.8 to 3.6. The average particle diameter thereof is in the range of 10 to 70 nm. The said toner particle is preferably a non-magnetic particle. By making use of the mono-component developer and the method for forming an image using it, charging of the toner, and carriage of the toner can be stabilized over a long period of time, and stable image formation can be obtained.
