Disclosed herein are an image-forming process which comprises steps of:uniformly charging a latent image carrier by a charging member disposed in contact with or in close vicinity to the latent image carrier,forming a latent image pattern on the latent image carrier by exposure,developing the formed latent image pattern with a developer composed of image-developing particles and conductive particles having an average particle size of smaller than that of said image-developing particles, thereby transferring at least said image-developing particles in the developer to the latent image carrier, andtransferring the image-developing particles transferred to the latent image carrier, to a transfer material; a developer for use in the image-forming process; and an image-forming system.
