A one-component developer comprising an external additive, and toner particles containing a binder resin and a colorant, wherein the external additive contains a titanium compound obtained by the reaction of TiO(OH).sub.2 and a silane compound, and an image forming method using the one-component developer are disclosed. The one-component developer and the image forming method provide excellent flow and a narrow charge distribution, can reduce fluctuation of the charge property due to the environmental change, and can thus form a high-quality image without fogging and the damage to a latent image retainer by filming can be prevented.
摘要:
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.
