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 fixing device includes a fixing belt that is rotatable and a pressure rotator that is pressed against the fixing belt to form a fixing nip therebetween. A polishing roller separably contacts the fixing belt and slides over an outer circumferential surface of the fixing belt while the polishing roller is pressed against the fixing belt. At least one support supports and stretches the fixing belt. A polishing aid, which is disposed opposite the polishing roller via the fixing belt, supports and stretches the fixing belt. The polishing roller is disposed opposite the polishing aid via the fixing belt to form a polishing nip between the polishing roller and the fixing belt while the polishing roller is pressed against the fixing belt. The polishing roller changes a rotation locus of the fixing belt along at least a part of a circumferential face of the polishing roller.

摘要： A fixing device includes an elastic rotator and a cooler disposed opposite the rotator to cool the rotator with cooling air. A mover contacts and moves the rotator to a first position where the rotator is disposed opposite the cooler with an increased first interval therebetween and a second position where the rotator is disposed opposite the cooler with a decreased second interval therebetween. A rectification plate is movably mounted on the cooler to contact the rotator constantly to guide the cooling air to the cooler.

摘要： A fixing device includes an endless fixing belt stretched taut across a first roller and a second roller and rotatable in a predetermined direction of rotation. A pressure rotator is pressed against the first roller via the fixing belt to form a fixing nip between the pressure rotator and the fixing belt, through which a recording medium is conveyed. A separation aid, disposed downstream from the fixing nip in the direction of rotation of the fixing belt to separate the recording medium from the fixing belt, includes a contact face contacting an inner circumferential surface of the fixing belt and a bulge disposed at a center of the contact face in a longitudinal direction of the separation aid. The bulge projects toward the inner circumferential surface of the fixing belt relative to each lateral end of the contact face in the longitudinal direction of the separation aid.

摘要： A fixing device includes a guide disposed downstream from a fixing nip formed between a fixing rotator and a pressure rotator, through which a recording medium is conveyed. A pressure rotator side separator, disposed downstream from the fixing nip in a recording medium conveyance direction, includes an opposed tip disposed opposite an outer circumferential surface of the pressure rotator and a separation-conveyance face that separates the recording medium from the pressure rotator. The opposed tip and the separation-conveyance face define a hypothetical circle having a curvature not smaller than 1/20 that intersects a guide face of the guide at an intersection at which a hypothetical tangent is tangent to the hypothetical circle. The hypothetical tangent and the guide face define a downstream intersection angle that is downstream from the hypothetical tangent in the recording medium conveyance direction and is greater than 90 degrees.

摘要： An image forming method to be performed by an image forming apparatus includes forming, transferring, fixing, and drying. The forming forms a foil portion to which foil is adhered on one surface of a recording medium. The transferring transfers an image to the one surface of the recording medium after the forming of the foil portion. The fixing fixes the image transferred to the one surface of the recording medium by the transferring of the image, to form a foil image portion including the foil portion and the image on the recording medium. The drying dries the recording medium on which the foil portion is formed, between the forming of the foil portion and the transferring of the image.
