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.

摘要： A developing method of the present invention is practicable with a developing unit of the type including a rotatable, nonmagnetic sleeve and a rigid metering member. A two ingredient type developer made up of magnetic carrier grains and toner grains is magnetically deposited on the sleeve. The metering member meters the amount of the developer deposited on the sleeve. The sleeve has surface roughness Rz ranging from 5 μm to 20 μm. The carrier grains each are covered with a coating layer containing at least binder resin and grains. The ratio of the diameter D of the individual grain contained in the coating layer to the thickness h of the binder resin layer lies in the range of 1

摘要： A developing device includes a developer carrier and a developer regulating member including a developer regulating part opposing a surface of the developer carrier to regulate the developer carried and conveyed by the developer carrier. The developer regulating member is formed from a single metallic member and includes a space that faces an inner surface of the metallic member. The space extends in a direction perpendicular to a moving direction of the surface of the developer carrier. The developing device can include a cooling device that cools the developer regulating member from an inner surface side of the metallic member facing the space.

摘要： In accordance with the present invention, in an image forming apparatus of the type developing a latent image formed on an image carrier, which moves at a linear velocity of 400 mm/sec or above, with a developer containing toner grains having a volume mean grain size of 5 &mgr;m to 10 &mgr;m and 60 number percent to 80 number percent of which has a grain size of 5 &mgr;m or below, the developer contains carrier grains having a weight mean grain size of 65 &mgr;m or below. When use is made of toner with a small grain size, the apparatus successfully obviates background contamination, toner scattering and sleeve contamination without regard to operation speed or environmental conditions.

摘要： 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 developing device includes a developer bearer to carry, by rotation, developer including toner and magnetic carrier to a developing range facing a latent image bearer; a casing including a developer container and an opening to expose a part of the developer bearer disposed in the casing; an opposing face of the casing including a conductive material and opposing to a surface of the developer bearer downstream from the developing range in a direction of rotation of the developer bearer; a developing bias source to apply a developing bias to the developer bearer; and an insulation layer disposed on the opposing face of the casing. The opposing face is disposed across, from the developer bearer, a casing gap sized to allow the developer borne on the developer bearer to contact the opposing face.
