A unit 24 is provided. Details of the operation panel unit 24 will be described later.

  As shown in FIG. 3, in the image forming unit 120, an exposure device 124 is fixed to a housing 122 that constitutes a main body, and controls the operation of each unit of the image forming device 10 at a position adjacent to the exposure device 124. A control unit 42 is provided.

  The exposure device 124 scans a light beam emitted from a light source (not shown) with a rotating polygon mirror (polygon mirror) based on the image information read by the document reading unit 12, and reflects the light beam with a plurality of optical components such as a reflection mirror. Thus, the light beams 126Y, 126M, 126C, and 126K corresponding to the yellow (Y), magenta (M), cyan (C), and black (K) toners are emitted. The light beams 126Y, 126M, 126C, and 126K are guided to the corresponding photoreceptors 128Y, 128M, 128C, and 128K, respectively.

  The aforementioned paper feed tray 26 is disposed below the image forming unit 120, and a pair of registration rolls 129 for adjusting the position of the leading end of the recording paper P is provided above the paper feed tray 26. ing. An image forming unit 130 is provided at the center of the image forming unit 120. The image forming unit 130 includes the above-described four photoconductors 128Y, 128M, 128C, and 128K, which are arranged in a vertical line.

The third intermediate transfer member 140 is in contact with the first intermediate transfer member 136 and the second intermediate transfer member 138. A transfer roll 142 is provided at a position facing the third intermediate transfer body 140. Here, the recording paper P is conveyed between the transfer roll 142 and the third intermediate transfer body 140, and the toner image on the third intermediate transfer body 140 is transferred to the recording paper P.

  A fixing device 146 is provided downstream of the paper transport path 144 through which the recording paper P is transported. The fixing device 146 includes a fixing roll 148 and a pressure roll 150, and heats and presses the recording paper P to fix the toner image on the recording paper P. The recording paper P on which the toner image is fixed is discharged to a discharge tray 28 provided on the upper part of the image forming unit 120 by a paper transport roll 152.

  Here, the image formation of the image forming unit 120 will be described.

  When image formation is started, the surfaces of the photoconductors 128Y to 128K are uniformly charged by the charging rollers 132Y to 132K. Light beams 126Y to 126K corresponding to the output image are irradiated from the exposure device 124 onto the charged surfaces of the photoreceptors 128Y to 128K, and electrostatic latent images corresponding to the respective color separation images are formed on the photoreceptors 128Y to 128K. The Developers 134Y to 134K selectively apply toners of respective colors, that is, Y to K, to the electrostatic latent images, and Y to K toner images are formed on the photoreceptors 128Y to 128K.

  Thereafter, a magenta toner image is primarily transferred from the magenta photosensitive member 128 </ b> M to the first intermediate transfer member 136. Further, a yellow toner image is primarily transferred from the yellow photoreceptor 128 </ b> Y to the first intermediate transfer member 136, and is superimposed on the magenta toner image on the first intermediate transfer member 136.

  On the other hand, similarly, a black toner image is primarily transferred from the black photosensitive member 128K to the second intermediate transfer member 138. Further, a cyan toner image is primarily transferred from the cyan photoconductor 128 </ b> C to the second intermediate transfer member 138, and is superimposed on the black toner image on the second intermediate transfer member 138.

  The magenta and yellow toner images primarily transferred to the first intermediate transfer member 136 are secondarily transferred to the third intermediate transfer member 140. On the other hand, the black and cyan toner images primarily transferred to the second intermediate transfer member 138 are also secondarily transferred to the third intermediate transfer member 140. Here, the magenta and yellow toner images that have been secondarily transferred first, and the cyan and black toner images are superimposed, and the color (three colors) and black full color toner images are formed on the third intermediate transfer body 140. It is formed.

  The secondary color transferred full-color toner image reaches the nip portion between the third intermediate transfer body 140 and the transfer roll 142. In synchronization with the timing, the recording paper P is conveyed from the registration roll 129 to the nip portion, and the full-color toner image is thirdarily transferred (final transfer) onto the recording paper P.

  Thereafter, the recording paper P is sent to the fixing device 146 and passes through the nip portion between the fixing roll 148 and the pressure roll 150. At this time, the full color toner image is fixed on the recording paper P by the action of heat and pressure applied from the fixing roll 148 and the pressure roll 150. After fixing, the recording paper P is discharged to the discharge tray 28 by the paper transport roll 152, and the formation of the full color image on the recording paper P is completed.

The CCD line sensor 40 is connected to the control unit 42 provided in the main body of the image forming apparatus 10. The reason why the light L is folded back by the plurality of mirrors in the reflecting portion 36 is that a predetermined optical path length is required for image formation on the CCD line sensor 40.

  Here, the scanning unit 32 moves in a direction orthogonal to the main scanning direction (sub-scanning direction: arrow X), so that the light emitted from the light source 39 irradiates the image recorded on the document 31 in a line shape. Is done. Subsequently, the reflected light from the document 31 is received by the CCD line sensor 40 via the reflecting portion 36 and the condensing portion 38. The CCD line sensor 40 outputs an electrical signal corresponding to the image density to the control unit 42 by photoelectric conversion. Then, the control unit 42 detects the image density of the irradiation area based on the obtained electrical signal. In this way, the image of the document 31 is read.

  On the other hand, a document set guide 30 is provided around the platen glass 22. The document set guide 30 has a slightly convex step from the platen glass 22, and the document 31 is easily positioned by aligning the corners of the document 31 so as to contact the step of the document set guide 30. .
