Methods and devices for creating an electrostatic force. An electrostatic platen device includes a continuous conductive layer; a first dielectric layer provided on a first surface of the continuous conductive layer; and a second dielectric layer provided on a second surface of the continuous conductive layer opposite to the first surface of the conductive layer. A power source is electrically coupled to the continuous conductive layer to generate an electric tacking field.

An inkjet printer includes an inkjet head configured to perform printing using ink along a main scanning direction onto a print medium by moving in the main scanning direction; a platen configured to support, from an opposite side of the inkjet head, a portion of the print medium being printed by the inkjet head by a printing portion supporting region extending in the main scanning direction; a print heater configured to heat the print medium via the printing portion supporting region; and a fan device extending in the main scanning direction, and configured to blow air out from a blower outlet for blowing the air toward a surface of the portion of the print medium supported by the printing portion supporting region.

A printing apparatus includes a platen that supports a recording medium, a printing head that reciprocates along the platen, and discharges a droplet onto the recording medium supported by the platen at least in a forward route or a backward route of the reciprocation, to perform printing, and an air blowing unit disposed on at least one of two sides of the platen in a reciprocation direction, that is a direction in which the printing head moves along with the reciprocation, and blows an airflow to a nozzle surface of the printing head that reciprocates.

Provided is an air jet emission method used in a recording apparatus. The recording apparatus performs predetermined printing by ejecting ink droplets from a recording head provided in an apparatus body onto a medium. The medium is fed into the apparatus body while being guided by a guide and is transported from an upstream side, which is one side with respect to the apparatus body, toward a downstream side, which is an opposite side with respect to the apparatus body. The air jet emission method comprises: emitting a jet of air onto a surface of the transported medium at a predetermined area over a heating device at the upstream side, thereby blowing dust off the surface of the transported medium. The heating device is provided in the guide so as to apply heat to the transported medium.

A sheet conveyance apparatus includes a first belt unit including a first belt, a second belt unit including a second belt that forms a nip portion for nipping and conveying a sheet with the first belt. The second belt unit includes at least one nip portion forming member forming the nip portion between the first belt and the second belt by abutting on an inner peripheral surface of the second belt and supporting the second belt, at least three supporting members disposed along a conveyance direction of the sheet in the nip portion, the at least three supporting members being in contact with surfaces of the nip portion forming member on a side opposite to the second belt at different positions in a width direction to support the nip portion forming member, and at least one connecting member connecting the at least three supporting members.

The present invention relates to a recording apparatus which includes: a set portion in which a roll-shaped recording medium is set; a transporting portion of the recording medium; a medium supporting portion which supports the recording medium; and a contact portion which is provided between the set portion and the medium supporting portion in a transporting direction of the recording medium and is biased to come into contact with the recording medium.

A first air blowing unit includes a first air blowing flow path. A second air blowing unit includes a second air blowing flow path and a communication port. The second air blowing flow path has a greater cross-sectional area for blowing air than a cross-sectional area of the first air blowing flow path. The first air blowing unit is located downstream from a carriage and upstream from a processing unit. A part or all of the second air blowing unit is located between a housing and the processing unit. The first air blowing unit and the second air blowing unit are provided at positions where the first air blowing unit and the second air blowing unit face each other in a first specific region along the scanning direction of the carriage. The communication port is located at least in the first specific region.

A drying apparatus includes a heater and a heat-transfer portion. The heat-transfer portion comes into contact with a second surface of a belt-like medium to transmit thermal energy supplied from the heater to the medium, the second surface being a surface on a back side of a first surface of the medium onto which ink is ejected. Further, the heat-transfer portion includes a base material portion, a first layer portion, and a second layer portion. The base material portion is provided closer to an opposing surface that opposes the heater than a contact surface that comes into contact with the medium. The first layer portion forms the contact surface and has higher abrasion resistance than the base material portion. The second layer portion is provided between the first layer portion and the base material portion and has higher heat conductivity than the base material portion.

An ink jet recording apparatus including an ink jet head having a nozzle for jetting, onto a base material, an ink that contains water and particles which contain a polymer P having an acid group and a polymerizable compound A, a scanning unit which is configured to cause the ink jet head to perform scanning in a scanning direction, a transport unit which is configured to transport the base material in a transport direction intersecting the scanning direction, a heating unit which is configured to heat a surface of the base material opposite to a surface on which the ink is to be landed, and a light source which is configured to, after the ink jetted from the nozzle is landed on the base material, irradiate the surface of the base material on which the ink is landed with an active energy ray.

A printing apparatus includes an ink ejector, a dryer, and a melting device. The ink ejector ejects an ink to an object on which a printed record is to be produced. The ink contains a medium and a fixing polymer. The dryer heats the object to expedite evaporation of the medium. The melting device is configured to irradiate the ink on the object with ultraviolet rays to subject the ink to heat that causes the fixing polymer to melt and to fix the ink to the object accordingly.
