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 electromagnetic wave irradiation device includes an irradiator which irradiates electromagnetic waves onto a liquid droplet which has been adhered to a recording medium, an irradiation controller which causes the irradiator to irradiate the electromagnetic waves periodically such that a frequency of an irradiation period in which the electromagnetic waves are irradiated is a predetermined frequency, and a time setting unit which sets a time ratio obtained by dividing a length of an irradiation time by the irradiator in the irradiation period by a length of a termination time during which the electromagnetic waves are not irradiated by the irradiator in the irradiation period to be a value of greater than or equal to 0.2 and less than or equal to 2.

摘要： 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.

摘要： A printing device includes heads that eject electromagnetic wave hardened inks toward a medium and irradiation sections respectively corresponding to the heads. The irradiation sections irradiate the electromagnetic wave hardened inks. A controller controls the heads and the irradiation sections. The controller, when printing, sequentially performs a method that includes the following operations. One head ejects a first ink in a first ejecting operation. An irradiation section corresponding to the head irradiates first electromagnetic ink in a first irradiation operation. A different head ejects another ink toward a pixel on the medium such that the other ink overlaps the first ink, in a second ejecting operation. An irradiation section corresponding to the other head irradiates the other ink in a second irradiation operation. The controller performs the operations such that a contact angle of the other ink relative to the first ink is greater than 90 degrees.

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.

A separator separates the recording medium, which has been passed through the nip portion, from one of the first rotative member and the second rotative member. The separator is provided with a first guide face extending in a first direction to guide the separated recording medium to an inlet of a subsequent stage of the image forming apparatus. The first guide face is provided with a rib extending in the first direction.

摘要： A printed article of the present invention is a printed article comprising: a substrate; (1) a toner image which is made of a thermoplastic resin containing wax component in an amount of 3 to 15 wt %, has a surface gloss level of 5–40, and is formed on the substrate by oilless fusing or (2) a toner image which is made of a thermoplastic resin containing wax component in an amount from 3 to 15 wt % and is formed on the substrate by oilless fusing to have a surface gloss level of 25–45 and have a flat surface with a lot of concavities; and a transparent film which is laminated to the surface of the substrate, on which the toner image is formed, via an adhesive layer. The toner image not projected is easy to see (read) because of no shin. The projected image of the toner image is also excellent both in visibility and transparency. That is, the printed article is useful as a printed article for OHP. The printed article is also useful as a high gloss printed article because the toner image has a gloss level corresponding to the gloss level of a non-transparent sheet so as to exhibit good color saturation.
