摘要： A heat roller for a fixing device included in an image forming apparatus has an insulation layer and a conductive layer sequentially formed on the inner periphery thereof. To form each of the insulation layer and conductive layer, a spray gun is inserted into the heat roller. Subsequently, paint, which is a liquid for forming the insulation layer or the conductive layer, is fed under pressure to the spray gun. The paint is radially jetted via the holes of the spray gun and evenly deposits on the inner surface of the heat roller. In this condition, the spray gun is moved in a preselected direction in order to coat the entire inner periphery of the heat roller. After the insulation layer has been formed and then sintered, the conductive layer is formed on the insulation layer and then sintered. The two layers can be formed in a short period of time and provides the heat roller with high quality at low cost. A method of producing the heat roller is also disclosed.

摘要： An ink mist collection apparatus for an ink jet printer comprises an ink mist adsorptive member interposed between a paper sheet and an ink jet head in order to adsorb an ink mist which is produced by an ink droplet ejected from the ink jet head upon impingement of the ink droplet on the paper sheet. The adsorptive member may be made up of a first adsorptive member and a second adsorptive member. The first member is disposed between the paper sheet and deflection electrodes to adsorb an ink mist while the second member is held in contact with the first member. The adsorptive member may be detachably mounted on a guide member which is located between the paper sheet and the ink jet head. The front end of the guide member adjacent to the paper sheet is protruded beyond the front end of the adsorptive member. The adsorptive member on the guide member may have its front surface spaced from the paper sheet more at its intermediate portion than at its opposite end portions.

摘要： A device incorporated in an electrophotographic image recorder for collecting toner particles, paper dust and so on which are removed from a photoconductive element by a cleaning device. The collecting device is constructed independently of the cleaning device. In a portion where the collecting device and cleaning device are connected to each other, a first and a second shutter which open and close respectively an opening formed through the cleaning device and an opening formed through the collecting device cooperate with each other. When the collecting device is connected to the cleaning device, the second shutter unblocks the associated opening before the first shutter does so. Conversely, when the collecting device is disconnected from the cleaning device, the second shutter blocks the associated opening after the first shutter has done so.

摘要： A charge detecting electrode unit is disclosed which is coupled to a platen shaft of an ink jet printer so as to be rotatable relative thereto for detecting a deflected position of charged ink particles. It includes a housing having an internal space in which a charge detecting electrode is centrally located. The housing is formed with an opening which receives flying ink particles, in its front surface. An electrically conductive layer is formed on and continuously extends across the internal wall surfaces and the external surface of the housing around the opening, and an electrically conductive and water absorbing sheet is attached to the outer periphery of the housing and is in contact with the conductive layer located around the opening which is connected to a grounding wire. The housing also includes a compartment which houses a water absorbing pad and which is open to the exterior of the housing. The water absorbing sheet extends into the compartment, and the pad housed within the compartment is in contact with the sheet. The compartment is normally closed by a closure. An isolating plate is disposed in the opening to divide it into an upper and a lower area, thus preventing an ink which has found its way into the lower area from being dispersed into the upper area.

摘要： An improved carriage assembly for use in ink jet printers is provided. The present ink jet printer carriage assembly includes a holder for holding an ink droplet projection nozzle and a charging electrode for charging ink droplets and the holder is so structured that it may be pivoted vertically as well as horizontally. Thus the ink jet projection direction may be adjusted with respect to its pitch direction as well as yaw direction. A deflection stage including a pair of oppositely arranged deflector electrodes is fixedly mounted on the carriage body; however, a gutter for collecting non-deflected ink droplets is adjustably provided. With such a structure, the whole assembly may be constructed quite with ease since minor mismatches may be corrected after assemblage; moreover, printed characters or images of excellent quality may be obtained.
