초록 ▼

A color image forming apparatus in which a charging, imagewise exposing and developing operations are repeated onto an image forming drum to register different colored toner images thereon and thereby to transfer simultaneously the toner images onto a recording sheet, includes four imagewise exposing units which are disposed inside the image forming drum and are fixed in a main body of the image forming apparatus. Two each of the exposing units and the developing units are disposed respectively on both sides with predetermined angles with respect to a vertical line passing through the center of the image forming drum. The apparatus further includes a transferring device and a cleaning device are disposed respectively with predetermined angles on different one side of the vertical line below a horizontal line intersecting with the center of the image forming drum.

대표청구항 ▼

A color image forming apparatus comprising: (a) an image forming body having a first surface and a second surface provided on a rear side of said first surface; (b) a plurality of chargers each for charging said first surface of said image forming body; (c) a plurality of image exposure means each for imagewise exposing said image forming body from said second surface to thereby form an electrostatic latent image on said first surface; (d) a plurality of developing means for developing each of the latent images formed on said first surface so that a plurality of different colored toner images are registered on said first surface, said plurality of developing means having a first, a second, a third and a fourth developing units in order along an outer circumference of said first surface of said image forming body, each of said first, second, third and fourth developing units having a developing sleeve for carrying each different colored developer thereon, wherein two each of said plurality of developing means are located on both sides with respect to a vertical line which passes through a center of said image forming body, and wherein said first, second, third and fourth developing units are located so that the following conditions are satisfied: qq0°to 20°, qq45°to 75°, where qqqq (e) a transferring means for transferring said plurality of toner images registered on said first surface of said image forming body onto a recording media at one time; and (f) a cleaning means for cleaning a residual toner on said first surface of said image forming body.
