DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an image forming apparatus for recording an image on a recording medium.
fin this case, as image forming apparatuses, an electrophotographic copying machine, a laser beam printer (LBP), an LED printer, a facsimile apparatus, a wordprocessor, and the like are included.
BACKGROUND ART
The background art of the present invention will be described below.
In recent years, a demand has arisen for a smaller image forming apparatus with improved operability. In order to satisfy such a demand on the market, the applicant of the present invention has previously made effective inventions, and disclosed them in Japanese Patent Application No. 60-123060 (Japanese Patent Application Laid-Open No. 61-279871; corresponding U.S. Pat. No. 4,873,548) and Japanese Patent Application No. 63-047637 (Japanese Patent Application Laid-Open No. 01-222269; corresponding U.S. Pat. No. 5,047,803).
The present invention has been made by improving the previous inventions. According to the present invention, there is provided an image forming apparatus which realizes a further reduction in size and an improvement in operability.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an image forming apparatus which realizes a further reduction in size.
It is another object of the present invention to provide an image forming apparatus which can be installed in a small installation space.
It is still another object of the present invention to provide an image forming apparatus which realizes an improvement in operability.
It is still another object of the present invention to provide an image forming apparatus in which a sufficiently large number of recording media on which images have been formed can be stacked in spite of a reduction in size.
It is still another object of the present invention to provide an image forming apparatus which realizes a low-profile structure by reducing the height of the apparatus.
According to one main aspect of the present invention, there is provided an image forming apparatus for performing a recording operation with respect to a recording medium, comprising image forming means for forming an image on a recording medium, recording medium receiving means for receiving the recording medium on which the image is formed by the image forming means, and laser beam emitting means, arranged below the recording medium receiving means, for emitting a laser beam in accordance with image information so as to cause the image forming means to form an image. Wherein the laser beam emitting means arranged below the recording medium receiving means emits a laser beam obliquely upward.
According to another main aspect of the present invention, there is provided an image forming apparatus which allows a process cartridge to be mounted therein and forms an image on a recording medium, comprising mounting means for allowing the process cartridge to be mounted therein, the process cartridge having an image bearing member and process means acting on the image bearing member, fixing means for fixing the image on the recording medium, and laser beam emitting means, arranged between the process cartridge mounted in the mounting means and the fixing means, for emitting a laser beam in accordance with image information.
According to still another main aspect of the present invention, there is provided an image forming apparatus which allows a process cartridge to be mounted therein and forms an image on a recording medium, comprising mounting means for allowing the process cartridge to be mounted therein, the process cartridge having an image bearing member and process means acting on the image bearing member, transfer means for transferring a toner image, formed on the image bearing member included in the process cartridge mounted in the mounting means, onto the recording medium, fixing means for fixing the image, transferred onto the recording medium by the transfer means, on the recording medium, laser beam emitting means, arranged between the process c
