摘要： In an ink jet recording apparatus in which a filter is placed in an ink supply route, when an ink flow is formed in the ink supply route by ink ejection during recording operations and so on, a valve does not contact firmly to the filter, but when an ejection recovery operation is performed and an ink flow velocity increases, the valve contacts firmly to the filter and covers up a part of the filter. With this structure and operation, the effective cross-section area of the filter decreases and hence, a given quantity of pressure difference is produced between the upstream side and the downstream side of the filter. As a result, bubbles unable to pass through the filter at recording operations can pass through the filter when ejection recovery operations are performed.

摘要： A recording medium in the sheet form is supplied into a designated direction guided by a sheet supply roller. An ink jet recording head in which a plurality of ink jet discharging orifices are arranged is placed in parallel with a surface of the recording sheet and in the direction perpendicular to the designated direction of supplying the recorded sheet. An adjustment screw is placed for correcting a warped shape of the ink jet recording head by means of displacing a neighbor of a central portion of a longer side of the ink jet recording head in the designated direction of supplying the recording sheet.

摘要： A copying machine includes a detachably mountable cassette which includes a photosensitive web as extending between a take-up roller and a supply roller provided in the cassette. The photosensitive web includes an imaging section which corresponds in length to transfer paper of maximum size usable in the copying machine and leading and trailing sections on both sides of the imaging section. Since the web is relatively short in length, it travels substantially at constant speed between the take-up and supply rollers so that there is no need to provide an extra device for maintaining a constant speed.

摘要： An electrophotographic apparatus is provided in which a toner image formed on a photosensitive member is initially transferred onto the surface of a transfer roller and then transferred onto a transfer sheet. Before the transfer step takes place, charge is injected into the toner image on the photosensitive member and the transfer roller is disposed close to the surface of the photosensitive member with a very small clearance. The photosensitive member has a conductive layer to which a bias voltage of the same polarity as the polarity of the toner charge can be applied. The transfer sheet is fed into the nib between the transfer roller and its abutting fixing roller, whereby the transfer and fixing of the toner image take place simultaneously.

摘要： In the method, two originals are placed side-by-side on the contact glass of an electrophotographic duplex copying machine and are scanned successively, in a single scanning operation, by the exposure optical system of the machine to form respective successive images on a photoconductive drum rotated past an image transfer device. Two transfer sheets are fed successively, with a short interval therebetween, from a primary supply device for transfer sheets, past the image transfer device in synchronism with the image formation on the drum, to provide duplex copies, having images in the same relation as that of the two originals, in a single copying cycle or process. By utilizing a secondary sheet supply device and a suitable switching device, images can be provided on both sides or surfaces of a transfer sheet or sheets. The duplex copying apparatus includes a novel sheet feed device effective to stack transfer sheets neatly.
