An image forming apparatus is provided with a rotatable upper cover, one surface of which serves as a first exit tray on which recording sheets are discharged with image sides face downward, the other surface of which serves as a second exit tray on which recording sheets are discharged with image sides face upward. Guide members which are activated in accordance with the rotation of the rotatable upper cover are provided above delivering rollers, thereby the recording sheets delivered by the delivering rollers are selectively discharged with the image sides either face downward to the first exit tray or face upward to the second exit tray.

An image forming apparatus provided with a process cartridge which contains at least an image carrying body fixed therein. The process cartridge is slidably provided to a main frame of the apparatus and is adapted to occupy two positions of a first position to perform the image forming and a second position suitable for maintenance and pulling out of the process cartridge for the main body. The process cartridge is drived automatically to the second position in each case of jam occurence in copy paper conveyance and maintenance.

A printer having an automatic removable cartridge. The cartridge has at least one of a photoreceptor, a developer, and a cleaner. The cartridge is automatically removed from the printer at a part when an operator opens the upper cover of the printer, or the printer senses an inside paper jam. The operator can remove the cartridge completely from the printer after it is partially removed by the automatic operation. The printer also includes an operating panel or the like to forcefully remove the cartridge from the printer by a command of the operator.

In an image forming apparatus, there is provided a multistage exit tray to receive printed recording sheets, which is located above an upper cover to access a conveyance path of the printed recording sheets within the apparatus by opening the upper cover upwardly. When the upper cover is opened, the exit tray is moved to a position where the exit tray does not interfere with the upper cover.

A color copier which can be adopted to a printer operation for a peripheral imaging machine. The color copier forms plural color component toner layers on a photoreceptor layer by layer at each rotation of the photoreceptor. In the mode that the color copier is used as a printer, the copier makes two pages of each of the color component toner layers corresponding to an image at one rotation of a rotatable photoreceptor, when the size of the image is not more than one half the maximum size that can be formed by the copier.

In an image forming apparatus having a detachable process cartridge in which an image carrier on which an electrostatic latent image is formed, and a developing unit which develops the electrostatic latent image so that a toner image can be formed, both integrally formed into one unit. There is provided a developer container including a discharge section which can be inserted into a supply opening of the developing unit, and a container in which a predetermined amount of developer is contained, wherein the developer container is provided to the toner supply opening of the developing unit and the developer is supplied into the developing unit housing when a toner stirring screw of the developing unit is rotated.

The invention provides a sheet feed cassette for holding various sizes of sheets to be fed to an image recording apparatus in a feed direction. The cassette comprises a first casing having a sheet placement area, and a second casing slidably connected to the first casing for expanding the area. The first casing is detachably mounted on the image recording apparatus.
摘要:
An image forming apparatus includes a process cartridge that incorporates a photoreceptor and a plurality of developing devices. The process cartridge is provided with a first driving shaft to drive the photoreceptor and a second driving shaft to independently drive the developing devices. When the process cartridge is mounted in the image forming apparatus which includes spaced apart first and second gears, the first and second driving shafts are coupled separately with the spaced apart first and second gears so that driving forces are separately transmitted to the first and second driving shafts. A flywheel is mounted on a third driving shaft that is coupled with the first driving shaft to drive the photoreceptor. Since the developing devices are constructed to receive a large number of different possible loads, the developers are placed in a condition where vibrations are created easily by the driving of the various possible loads. The driving of the photoreceptor is arranged to be independent of the driving of the developing devices so that vibrations generated by the driving of the developing devices are not transmitted to the photoreceptor. Furthermore, the flywheel is provided on the third driving shaft, and a third gear is mounted on the third driving shaft. Since the third gear is coupled with the first driving shaft to drive the photoreceptor, the rotation of the photoreceptor will be smoothed out by the presence of the flywheel.
