Abstract: An electrostatic image developing toner includes a toner mother particle that contains a binder resin and a releasing agent; and an external additive that contains a zinc compound particle and a silica particle, wherein the zinc compound particle has a number average particle diameter of from about 2.0 ?m to about 10.0 ?m, the silica particle has a number average particle diameter of from about 60 nm to about 250 nm, the number of free zinc compound particles in all toner particles is from about 0.2% by number to about 1.0% by number, and the free zinc compound particle has an average circularity of about 0.6 or less.

Abstract: An image forming apparatus includes a photosensitive medium to be charged with a predetermined potential by a charging member, an exposing unit to expose the photosensitive medium to vary a charging level of the photosensitive medium, a developing unit to form an image for one or more colors on the photosensitive medium, a transfer medium to transfer the image from the photosensitive medium, a cleaning unit to clean the transfer medium, and a controller to control an optical power of the exposing unit to be lower than that during forming of the image when a toner band is applied to lubricate at least one of the cleaning unit and the transfer medium.

Abstract: An image forming apparatus including an image bearing member that bears a latent image and has a surface layer; a charging device that charges the surface of the image bearing member: a latent image forming device that forms the latent image on the surface of the image bearing member; a development device that develops the latent image formed on the surface of the image bearing member with a development agent to form a toner image thereon; a transfer device that transfers the toner image to a transfer medium; a cleaning device that removes residual toner remaining on the surface of the image bearing member after transferring the toner image to the transfer medium; and a protection agent supplying device that supplies a protection agent to the surface layer of the image bearing member that forms a protection layer thereon, wherein the protection agent comprises a metal soap and boron nitride and the amount of the boron nitride in the protection layer applied to the image bearing member after image formation is

Abstract: A cleaning station for removing particulate material from a moving web in an electrographic printer/copier includes a customer-replaceable web-cleaner device with a support bracket/backup shoe assembly. A quick disconnect feature enables the cleaner cover to be de-coupled from the cleaner body to allow the debris to be easily removed with replacing the web-cleaner. The cleaner has a cleaner sump that is spring loaded to force contact of four strategically placed stops in the sump with a stationary back up shoe assembly allowing for higher precision of blade engagement with a transport web or a photoconductor. The web-cleaner has two wiper blades, each having each having a distinguishment such that the distinguishment distinguishes one wiper blade from the other wiper blade when the blades are locked into the cleaner sump by springs, to facilitate material removed from the web. The wiper cleaning blades and the cover assembly are easily replaceable by the operator in the correct order.
