Abstract:
An image forming apparatus includes a fixing liquid applicator to apply a fixing liquid to a recording medium before a toner image is transferred on the recording medium, a transfer device to transfer a toner image from a toner image bearing member onto the recording medium applied with the fixing liquid, and a fixing device to fix the toner image on the recording medium by heating. The fixing liquid applicator includes an application member disposed opposing a face of the recording medium on which the toner image is transferred to apply to the recording medium the fixing liquid borne on a surface of the application member, a supply unit to supply the fixing liquid to the application member, and a sealing device to form along with the application member a sealed space in which the supply unit and the fixing liquid to be supplied to the application member are sealed.
Abstract:
An operator guidance system includes a detection unit, a control unit, and an operation indicator. The detection unit is disposed in an image forming apparatus to output a combination of detection signals, and includes one or more media sensors, and one or more opening sensors. The one or more media sensors are disposed along a media conveyance path to output a media detection signal. The one or more opening sensors are disposed adjacent to an openable structure to output an opening detection signal. The control unit is connected to the detection unit to determine guidance to be provided to an operator based on the combination of detection signals, and includes a memory and a controller. The operation indicator is connected to the control unit to indicate the identified operation to the operator.
Abstract:
An information recording medium includes a transparent recording member and a substantially non-transparent member. The transparent recording member has at least one transparent area and a concavo-convex pattern on a first surface thereof while bearing a reverse toner image on a second surface thereof. The substantially non-transparent member is formed on the second surface of the transparent recording member.
Abstract:
An image forming apparatus including a conveyance unit to convey a transfer medium, a first image forming unit to form a monochrome image transferred at a first transfer position onto the transfer medium, and a second image forming unit disposed downstream from the first image forming unit in a direction of conveyance of the transfer medium, including an intermediate transfer body to form a multi-colored toner image on the intermediate transfer body. The multi-colored toner image is transferred onto the transfer medium at a second transfer position. The conveyance unit is separated from the intermediate transfer body at the second transfer position in a monochrome mode to form the monochrome image using only the first image forming unit, and contacts the intermediate transfer body at the second transfer position in a full-color mode to form a full-color image using both the first and second image forming units.
Abstract:
A sheet bonding machine for bonding first sheet and a second sheet together includes a transport part, an angling member, and a pressure bond part. The transport part is configured to transport the first sheet and the second sheet and contact the first and the second sheet against each other at a predetermined angle. The angling member is configured to bend at least one of the first sheet and the second sheet. The pressure bond part is provided downstream of a contact position between the first sheet and the second sheet and configured to bond together with pressure the first sheet and the second sheet contacted against each other.
Abstract:
An image forming apparatus includes an image carrying member, a developing unit, an image density detector, a toner concentration detector, a toner concentration controller, and an output adjustment unit. The image carrying member forms a reference latent image pattern. The developing unit develops the reference latent image pattern as a reference image pattern with a two-component developer. The image density detector detects an image density of the reference image pattern. The toner concentration detector detects a toner concentration in the two-component developer. The toner concentration controller controls the toner concentration based on the image density detected by the image density detector. The output adjustment unit adjusts a toner concentration sensing level of the toner concentration detector with a sensor control voltage. The toner concentration is controlled by a target voltage with reference to the image density. The toner concentration range is changed by changing the sensor control voltage.
Abstract:
A sheet processing method including superimposing a transparent sheet having a mirror image thereon on a non-transparent sheet so that a surface of the transparent sheet having the mirror image faces the non-transparent sheet with an adhesive medium therebetween. An image forming apparatus includes an image forming means for forming a mirror image on a transparent sheet, and a heating and pressing means for applying heat and pressure to the transparent sheet and a non-transparent sheet on which the transparent sheet is superimposed so that a surface of the transparent sheet having the mirror image faces the non-transparent sheet. The non-transparent sheet includes a heat-sensitive adhesive layer including an adhesive medium including a thermoplastic resin and a solid plasticizer, on a surface facing the surface of the transparent sheet having the mirror image.
Abstract:
A developing device for feeding a developer stored therein to an image carrier of the present invention includes a sleeve facing the image carrier for causing the developer deposited thereon to contact a latent image formed on the image carrier. A regulating member faces the sleeve for regulating the thickness of the developer that forms a layer on the sleeve. A guide member has a guide surface for guiding the developer regulated by the regulating member toward the surface of the image carrier. The guide surface has a conductive surface facing the sleeve. The developing device protects the image carrier from defective images ascribable to impurities, which include deteriorated toner and paper dust, without resorting to a filter mechanism or a bias for collection.
