Color image forming apparatus including process cartridge

A color image forming apparatus for forming color toner images on a sheet of paper, comprising:

• an apparatus body;
• a photoconductive medium in said body for bearing an electrostatic latent image thereon;
• a plurality of developing devices in said body for developing the latent image on said photoconductive medium;
• an intermediate transfer medium in said body for receiving developed latent images from said photoconductive medium and forming composite toner images thereon;
• a front frame of said body positioned adjacent said intermediate transfer medium;
• a paper feed device positioned in a lower portion of said body;
• a paper output tray positioned in a upper portion of said body;
• and
• a paper transporting path between said paper feed device and said paper output tray, said paper transporting path passing between said intermediate transfer medium and said front frame, wherein said intermediate transfer medium comprises an intermediate transfer belt and two vertically spaced rollers which support said intermediate transfer belt.

A color image forming apparatus for forming color toner images on a sheet of paper, comprising:

• an apparatus body;
• a process cartridge in said apparatus body which includes at least a photoconductive medium for bearing an electrostatic latent image thereon;
• a paper feed device in said body which is provided in a lower position of said body;
• a paper output tray in said body which is provided in a upper position of said body;
• a paper transporting path between said paper feed device and said paper output tray;
• a front frame rotatably supported on said body, wherein said paper transporting path is exposed when said front frame is opened;
• a sub-frame which supports said process cartridge and is supported on said body for pivotal movement;
• and
• a developing device in said body, said developing device being exposed when said sub-frame is opened.
