A plasma processing apparatus has a chamber which houses therein a plasma processing region and a plasma generating region spaced therefrom. An object such as a semiconductor wafer, which has surface irregularities including lands, is placed in the plasma processing region. When a plasma is generated in the plasma generating region with a processing gas composed mainly of an argon gas being introduced into the chamber, the corner edges of the lands of the object are etched into a taper shape, and the material etched away from the object is deposited between the lands.

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.

A fixing apparatus, includes a fixing roller which has a middle portion and both end portions in an axis direction thereof, a pressing roller which is brought into press contact with the fixing roller for rotating so that a press contact portion is formed, an exfoliating member which exfoliates a sheet-like record medium from a surface of the fixing roller after the record medium is passed through the press contact portion, and restricting members which is provided at both end portions of the exfoliating member, and is brought into contact with the surface of the fixing roller so that an interval between the surface of the fixing roller and the exfoliating member is restricted. The middle portion of the fixing roller is smaller than the both end portions of the fixing roller in a diameter. The restricting members are brought into contact with first portions of the fixing roller other than second portions of the fixing roller in which end edge portions of the pressing roller are brought into contact with the fixing roller.

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.

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.

A nozzle surface (nozzle plate) of a printing head which ejects UV-curable ink from a nozzle is tilted with a predetermined inclination angle θ with respect to the recording surface of a recording sheet so as to face the opposite side to an ultraviolet irradiator. In this manner, it is difficult for the ultraviolet light which is radiated from the ultraviolet irradiator, and is reflected on the recording sheet to input to the nozzle plate, and it is possible to prevent ink in the nozzle from being thickened, or being cured due to the ultraviolet light.

A printing device that forms a background by a first ink and images on the background by a second ink includes a head having first and second nozzle lines that eject, respectively, the first and second inks. The inks are ejected as the head moves, with respect to a medium, in a main scanning direction intersecting the first and second nozzle lines. A transport section transports the medium in a sub-scanning direction along the first and second nozzle lines. In an ejecting operation, the first and second inks are ejected in the relative movement in the main scanning direction and the relative transportation in the sub-scanning direction is performed. In the sub-scanning direction, first and second nozzle line used areas are set where the first and second inks, respectively, are ejected from the first and second nozzle lines. A nozzle unused area is defined therebetween.

A liquid ejecting apparatus includes a liquid ejecting head which ejects liquid containing metallic particles from a nozzle with respect to a target, the liquid ejecting head being disposed so that the nozzle opens facing a direction higher than a horizontal direction, and ejects the liquid from the nozzle facing the direction higher than the horizontal direction, thereby attaching the liquid to the target.

A fluid ejecting apparatus includes: a fluid ejecting unit that ejects a colored fluid and a colorless fluid toward a fluid ejection target medium; an irradiating unit that irradiates ultraviolet rays onto a fluid that lies on or over the fluid ejection target medium so as to cure the fluid; and a controlling unit that controls the fluid ejecting operation of the fluid ejecting unit and the ultraviolet ray irradiating operation of the irradiating unit. The controlling unit performs control so that the colorless fluid is ejected on an image that is made of the colored fluid that landed on the fluid ejection target medium. After the start of the agglomeration of the colorless fluid that landed on the image, the controlling unit performs control so that ultraviolet rays are irradiated onto the colorless fluid.
