ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an image forming apparatus such as a copier or a printer which uses an electrostatic recording process, an electrophotographic process, or the like.
2. Related Background Art
Conventionally, an image forming apparatus such as a printer, a copier, or a facsimile is provided with a recording material supplying portion and an image forming portion. The recording material supplying portion stores a large number of sheet-like recording materials (mediums on which images are formed) and separates and conveys the recording materials one by one. On the other hand, the image forming portion forms an image with a toner or ink on a surface of the recording material supplied by the recording material supplying portion.
In such an apparatus, the recording material supplying portion for supplying a recording material to the image forming portion is constituted as a unit having a plurality of cassettes and is arranged below the image forming portion, whereby a width of the apparatus is reduced.
However, since a size of the recording material is smaller than the area of the base of the image forming portion, there is still left room for reduction of a space.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an image forming apparatus with a small installation area.
It is another object of the present invention to provide an image forming apparatus including:
a recording material unit which stores recording materials;
an image forming unit which is arranged above the recording material unit and forms an image on the recording material supplied from the recording material unit; and
a power supply unit for supplying electric power to the image forming apparatus,
in which the power supply unit is constituted as a unit integral with the recording material unit and is arranged below the image forming unit.
Further objects of the present invention will be apparent in the following description.
