Abstract: An image forming apparatus includes an apparatus main body and an original reading device disposed on top of the apparatus main body. A sheet supply cassette, a sheet discharge tray, an original feed tray, and the original discharge tray are oriented such that their lengthwise directions are aligned with the first horizontal direction, and are arranged to overlap with one another in the vertical direction. A pair of side walls is disposed at both widthwise ends of the sheet supply cassette, the sheet discharge tray, the original feed tray, and the original discharge tray. The both widthwise ends of these components are formed as edge portions. The pair of side walls covers an entire length of each of the edge portions, thereby supporting all of the sheet supply cassette, the sheet discharge tray, the original feed tray, and the original discharge tray.

Abstract: When a guide lever is in a toner open position, a space is formed between an upper surface of the guide lever and a lower surface of a flat bed unit as a part of a transport path of a paper. Therefore, the paper is turned forward around in a generally U-shape in the transport path, and passes over a toner cartridge, then is ejected to an ejection tray. So the transport path can be increased in radius of curvature at the U-turn point thereof, and whereby a reliable feed of the paper with a reduced risk of paper jam can be achieved. Further, since a scanning unit is disposed below and adjacent to a process cartridge and the ejection tray so that it can overlap with the process cartridge and the ejection tray, and is disposed adjacent to a feed tray so that it can overlap upwardly with the feed tray, reduction in size of a laser printer can be achieved.

Abstract: Upon depression of a copy execution button 8, an image recording apparatus 1 executes a copy processing by causing an ink jet printer 37 to record the image data read by an image reading part 21 on recording paper. Alternatively, upon depression of the copy execution button 8, the image recording apparatus 1 causes the ink jet printer 37 to record the image data transmitted from a hand-scanner 2 through a transmission cable K1 connecting the image recording apparatus 1 and the hand-scanner 2 which is capable of reading image information on an original.

Abstract: A transfer bias applying power supply 81 applies a transfer bias current of a fixed amount to a transfer roller 31 by executing a constant current control operation. A voltmeter 78 measures the amount of voltage generated by the transfer roller 31. The generated voltage amount indicates the resistance of the transfer roller 31. A sheet type detecting program is executed to detect the size and thickness of a sheet 3. An amount of transfer bias current is selected dependently on: the detected size and thickness of the sheet 3; and the measured generated voltage amount. The transfer bias applying power supply 81 is controlled to apply the transfer roller 31 with the transfer bias current of the selected amount.

Abstract: A picture signal processing apparatus and method is presented that determines whether there is an odd or even-number field signal in the picture signals received, by referring to flags that are turned on or off in accordance with the result of odd and even-number field detection. If the odd and even-number field flags are on, an image processing operation A is performed. If the odd-number field flag is on and the even-number field is off, an image processing operation B is performed. If the odd-number field flag is off and the even-number field is on, an image processing operation C is performed. In accordance with whether there is an odd or even-number field signal in the received picture signals, an appropriate image processing operation is selected from the different operations. That is, the received picture signals are processed in a mode suitable to the signals, so as to generate suitable image data.

The cleaning device absorbs residual toner left on the surface of the photosensitive drum after a transfer process from the surface of the photosensitive drum by using a potential difference from the photosensitive drum in an absorption mode and for blowing off and dispersing the absorbed toner to the surface of the photosensitive drum by using another potential difference from the photosensitive drum in a blowing-off mode.

Abstract: An image recording apparatus for recording a latent image of an original color image onto an elongated web photosensitive recording medium by separating the color of the color image into a plurality of colors by creating a plurality of mask members, and exposing the same part of the photosensitive recording medium to each of the plural mask members by appropriately colored light. The tension applied to the photosensitive recording medium is detected by a sensor at a slack buffer location between an exposing unit and a developing unit when development of one latent image and exposure of a following latent image are carried out simultaneously. The driving speed for a motor for driving the buffer is changed by a control unit according to the tension of the photosensitive recording medium as detected by the sensor.
