摘要:
A sheet conveyance guide includes a sheet material. The sheet material has a surface to face a sheet when the sheet conveyance guide guides the sheet travelling in a conveyance direction. The sheet material has irregularities over a whole area of the surface.

A method for manufacturing a removable information sheet includes: forming a toner image on a recording medium; applying an energy-ray-curable pressure-sensitive composition precursor onto the medium to form an energy-ray-curable pressure-sensitive composition precursor layer; irradiating, with an energy ray, the medium to cure the layer and form an energy-ray-curable pressure-sensitive composition; and attaching faces with the composition and pressure-bonding the faces. A region size of a toner-image flat part is 200 μm or less in the image, which is determined by a measurement method including: defining a site at a depth of 2 μm or more from a surface of a solid part of the image as a recess; defining a site other than the recess as the flat part; acquiring and binarizing a micrograph of the solid part; drawing circles out of contact with the recess; and defining a largest circle diameter as the size of the flat part.
摘要:
A device that estimates carrier deterioration indicating a degree of deterioration of carrier inside a developing device using a two-component developer includes a first carrier deterioration calculation unit, a second carrier deterioration calculation unit, and a carrier deterioration degree output unit. The first carrier deterioration calculation unit uses toner consumption and agitation time to calculate a first carrier deterioration degree indicating a degree of carrier deterioration caused by a spent phenomenon. The second carrier deterioration calculation unit uses the toner consumption and the agitation time to calculate a second carrier deterioration degree indicating a degree of carrier deterioration caused by a carrier abrasion phenomenon. The carrier deterioration degree output unit uses the toner consumption to select one of the first carrier deterioration degree and the second carrier deterioration degree, and outputs the selected carrier deterioration degree.
摘要:
A developing device includes a developer bearer disposed facing a latent image bearer in a developing range to transport developer by rotation, a support to support the developer bearer and including a holder mount, a rod-shaped developer regulator disposed facing a surface of the developer bearer across a gap, and a holder secured to the holder mount of the support to hold the rod-shaped developer regulator. The rod-shaped developer regulator extends in an axial direction of the developer bearer.

An image forming method for an image forming apparatus having a fixing rotator and a pressure rotator opposite the fixing rotator includes transferring white toner and color toner onto a surface of a metallic sheet having a thermal conductivity of 0.34 W/m·K or less as measured by hot-wire method to form an unfixed color toner layer layered on an unfixed white toner layer on the metallic sheet and conveying the metallic sheet, with the surface on which the white toner layer and the color toner layer are transferred facing the fixing rotator, between the fixing rotator heated and the pressure rotator to fix the white toner layer and the color toner layer onto the metallic sheet.
摘要:
An image forming method includes forming, fixing, and applying. The forming forms a toner image on a recording medium by an image forming device. The fixing fixes the toner image on the recording medium with heat by a fixing device. The applying applies an electric charge by a charge applying device to the recording medium on which the toner image has been fixed by the fixing device, in a state in which an output-adjustable power source for the charge applying device has an electric current that is controlled to be constant.
