摘要： A liquid ejecting apparatus includes: a head that ejects liquid to be cured by receiving irradiation of an electromagnetic wave onto a medium; a provisional-curing irradiation section that emits a first electromagnetic wave to a dot formed on the medium by the liquid; and a main-curing irradiation section that emits a second electromagnetic wave, which has irradiation intensity higher than that of the first electromagnetic wave, to the dot to which the first electromagnetic wave is emitted. When the main-curing irradiation section emits the second electromagnetic wave, a dot forming surface of the medium faces the lower side in the direction of gravity.

摘要： A three-dimensional molding apparatus for binding powder with a binding liquid to mold a three-dimensional object. When the three-dimensional object is cut into cross-sectional layers, a cross-section data generating unit generates cross-section data for each of the layers. A cross-sectional member forming unit spreads the powder so as to have a substantially uniform thickness to form a powder layer and supplies the binding liquid to the powder layer on the basis of the cross-section data to form a cross-sectional member corresponding to one layer of the three-dimensional object. A three-dimensional object molding unit forms a new powder layer on the powder layer in which the cross-sectional member is formed, supplies the binding liquid to the new powder layer on the basis of the cross-section data to form a new cross-sectional member, and laminates the new cross-sectional member on the previous cross-sectional member, thereby forming the three-dimensional object.

摘要： An image forming apparatus which is able to form either single or double sided copies on a recording medium while achieving an excellent image quality in either a matted or glossy finish. The image forming apparatus includes a fixing portion in which a first roller includes a first temperature and hardness for forming a matted image, whereas a second roller includes a higher temperature and hardness for forming a glossy image. Alternatively, or in addition, to different hardness and temperatures, the recording medium can be conveyed at a first speed to form a matted image, and a slower speed to form a glossy image. The image forming apparatus further includes an inverse and re-fixing sub-mode, which utilizes an inverting and returning passage, for reducing the curl in a recording medium, and thus also reducing the instances in which clogging takes place. The inverting and returning passage has a length sufficient to accommodate a plurality of recording mediums. Moreover, the image forming apparatus is provided with first and second discharge passages so that if one passage is clogged, the other can be used to discharge recording mediums. A switching means selects, based on detection sensors, through which discharge passage a recording medium is fed. The operations of the image forming apparatus are coordinated by a control unit.

摘要： An image formation apparatus is provided having a continuous form photosensitive member positioned to move along a pre-defined transfer path. An image is exposed on to a portion of the photosensitive member along the transfer path. A heat developer heats the exposed image portion and intercepts the heat to an unexposed portion of the photosensitive member. The heat developer has a cylindrical housing having a heated portion arranged along a longitudinal axis of the cylindrical housing and a heating element in surface contact with and for heating exposed portions of the photosensitive member. The cylindrical housing also has an unheated portion arranged along the longitudinal axis of the cylindrical housing and separated from the heated portion by a thermally insulative material. A thermal shield is selectively movable along the transfer path in synchronism with and in the direction of transfer of the photosensitive member between a heat shielding position and a non-heat shielding position for protecting and preserving unexposed portions of the photosensitive member. The thermal shield has a curved heat shield position adjacent to the heating element and movable concentrically about the longitudinal axis between the heat shielding position between the heating element and photosensitive member and the non-heat shield position.
