Abstract
An image forming apparatus is of the type in which a plurality of toner images are successively transferred onto a printing medium from a plurality of image carriers one above another. A toner image built on each of the image carriers is transferred onto the printing medium at a predetermined image transferring position. The apparatus is so constructed that each of the image carriers and printing medium conveying means are driven by single driving power transmitting means which is caused to move endlessly.
Claims18
A color image forming apparatus of the type in which a multi-color image is formed by successively transferring a plurality of different color toner images onto a printing medium one above another, comprising:
- a plurality of rotatably supported image carriers including driving power receiving portions;
- toner image forming means located opposite each of said image carriers for forming a color toner image on the latter;
- image transferring means disposed at an image transferring position, where a toner image formed on each of said image carriers is transferred onto the printing medium;
- printing medium conveying means for endlessly moving under the effect of driving power to successively convey the printing medium to the image transferring position for each of said image carriers;
- and
- driving means common to said plurality of image carriers and to said printing medium conveying means for providing driving power for said image carriers and said printing medium conveying means, respectively.
