A toner density is calculated from outputs of light-receiving elements based on a difference between a reflection property of a supporting member and a reflection property of a toner pattern. Light-emitting elements aligned in one direction that is inclined to a sub-direction emit a detection light in such a manner that a distance between adjacent spots falling on the supporting member in a second direction is equal to or smaller than a width of the toner pattern in the second direction. The light-receiving elements receive a reflected light reflected from the supporting member and / or the toner pattern. The light-receiving elements are aligned, opposed to the supporting member, in a one direction corresponding to the light-emitting elements.

A release-promoting agent is configured to be applied to a heating member in a fixing device that presses the heating member against a recording medium on which a toner image is formed and fixes the toner image to the recording medium, to promote release of the toner image from the heating member. The release-promoting agent is formed with a mixture of a dimethyl polysiloxane and an amino group-containing dimethyl polysiloxane represented byrespectively, where b≠0, and c>1000.

A remanufactured laser printer toner cartridge incorporates a used doctor blade and / or a used wiper blade. The used doctor blade has been adapted and oriented to make contact with a developer roller or a magnetic roller along a previously unused portion of the doctor blade's metering surface to utilize a new fresh metering surface. The used wiper blade has been adapted and oriented to make contact with a photoconductive drum along a previously unused portion of the wiper blade's wiping surface to utilize a new fresh wiping surface. The invention extends the effective life of doctor blades and wiper blades by utilizing previously unused working surfaces.It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not to be used to interpret or limit the scope or meaning of the claims.

Reactive inks and methods of generating an image on a substrate using both reactive and heat activated inks are presented. An image is printed on a substrate, without reacting the reagents in the ink. Subsequently, the reagents are reacted to fix the image to a substrate, with substantial permanency and fastness. Sublimation or similar heat activated dyes are printed are also printed on the substrate. The sublimation or similar heat activated dyes are activated, and have an affinity for polymer that is applied to the substrate.

A fixation device configured to fix on a medium a resin fine particle that contains a resin, by providing a fixation fluid on the resin fine particle on the medium which fixation fluid contains a softening agent that softens the resin fine particle by dissolving or swelling at least one portion of the resin, water and a foaming agent that comprises a salt of aliphatic acid, wherein the fixation device comprises a foam-like fixation fluid producing part configured to produce a foam-like fixation fluid, a layer thickness controlling part configured to control a layer thickness of the produced foam-like fixation fluid, and a provision part configured to provide the layer-thickness-controlled foam-like fixation fluid on the resin fine particle on the medium.

Methods of making fibrous webs having a visible transparency variation image and products constructed from such methods are generally disclosed. The variation in transparency creates a transparency variation image in the fibrous substrate in the form of a false watermark and / or a false shadow mark. In the method disclosed, a transfer sheet having a transfer coating is utilized. A portion of the transfer coating is removed from the transfer sheet by heat transfer with a printable sheet having a toner image applied thereon. The transfer coating of the transfer sheet includes a powdered thermoplastic polymer and a film-forming binder. The film-forming binder can have a melting point that is less than that of the powdered thermoplastic polymer. In the final step of the method, the remaining transfer coating is transferred to a fibrous substrate to form the transparency variation image in the fibrous substrate.

A method for producing a printed material, a method for producing a dye-printed material, a printing apparatus, and a dye-printing system have a good transfer property when a dry toner including a dye is electrostatically transferred to a base material, such as a fabric, based on an electrophotographic system or the like. The methods include a step of providing at least one type of dry toner containing a dye component and a binder resin to a charged body, a step of transferring the dry toner from the charged body to a base material, and a step of fixing the dry toner on the base material. In the transfer step, an electric field is applied between the charged body and the base material to fly the dry toner on the charged body from the charged body to the base material.
