An image forming apparatus includes a printer unit configured to form a toner image on a recording material, the printer unit including a fixing portion configured to heat-fix the toner image on the recording material; a reader unit provided above the printer unit and configured to read an image of an original, the reader unit including an image sensor configured to optically read the original; wherein in a side of the reader unit opposed to the printer unit, there are provided a suction opening configured to suck air from an outside of the reader unit and a discharging opening configured to discharge the air to an outside of the reader unit, and wherein an air flow path connecting the suction opening and the discharging opening overlaps with an entirety of the image sensor in a main scan direction which is an axial direction of the image sensor.

Image forming apparatus with printer unit and air-cooled reader unit

An image forming apparatus provided with an image forming portion for forming an image on a sheet, a sheet containing portion provided below the image forming portion and containing sheets to be supplied to the image forming portion, and a re-conveying path for again conveying the sheet having an image formed thereon to the image forming portion, wherein a portion of the lower side of the re-conveying path is disposed in the sheet containing portion.

Image forming apparatus

A sheet feeding apparatus with a sheet containing tray adapted to support a plurality of sheets and being shiftable between a sheet supplying position and a waiting position, a sheet supply roller for feeding out the sheet supported by the sheet containing tray at the sheet supplying position, a driving force transmitting device connected to the sheet supply roller and adapted to transmit a driving force from a drive source, and a holding device connected to the driving force transmitting device so that the sheet containing tray is shifted to the sheet supplying position by the driving force transmitted to the sheet supply roller and capable of holding the sheet containing tray at the sheet supplying position while the plurality of sheets are being supplied by the sheet supply roller.

Sheet feeding apparatus having the ability to retract the sheet supply

An electrophotographic copying apparatus is provided with a first body and a second body, the first body having a photosensitive member, a light source for exposing an original, an original supporting table movable relative to the light source with the original supported thereon, and a first optical system for projecting a first image information light reflected from the original onto the photosensitive member. The second body has a second optical system for projecting a second image information light onto the photosensitive member in the first body. Two copying modes are provided: a first mode for copying by the first image information light, and a second mode for copying by the second image information light. In the second mode, a controller positions a shutter member for blank exposure in the optical path in its retracted position prior to the copying in the second mode. Thus, solving the optical problems on the copying apparatus side and on the apparatus side for operating the recording medium and the higher functionalization of an optical system and/or the movement range of the movable original supporting table is changed during the original copying and during the copying of the recording medium to thereby enable the efficient use of the space.

Electrophotographic copying apparatus for copying an original placed on

The image-forming apparatus comprises a first frame, a recording electrode with an image formation voltage applied thereto, a belt-like recording medium disposed facing the charging electrode and toner transporting means for supplying toner to a space between said recording electrode and recording medium. For the positioning of the belt-like recording medium with respect to the charging electrode, a second frame for movably supporting the recording medium is provided together with the recording electrode in the first frame. An recording medium feed member is urged against the second frame at a predetermined position thereof. Thus, the recording electrode and recording medium can be positioned relative to each other without need of any particular adjustment whenever the recording medium is replaced.

Image-forming apparatus

An image forming apparatus which employs a recording method that uses electrically conductive developer, and a developing device for use in the image forming apparatus. A magnetic field is generated in an area having a width larger than that of a group of electrodes at the position of the electrode group so as to prevent the developer which has been passed over the electrodes from flowing outside of an image area at the downstream side of the group of electrodes.
