Abstract
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.
