The present invention relates to an electrophotographic color image forming apparatus using a tandem-drum development, an indirect image-transfer method, and a vertical sheet supply path. An intermediate image-transfer member is angled relative to a horizontal line such that a rear side of the intermediate image-transfer member away from a recording sheet is lifted and a front side of the intermediate image-transfer member closer to the recording sheet is lowered. Further, image creating mechanisms of the tandem-drum development are aligned and arranged in parallel to a moving image transfer bed of the intermediate image-transfer member, such that one of the image creating mechanisms firstly forming an image faces the rear side of the moving image transfer bed and another one of the image creating mechanisms lastly forming an image faces the front side.

A facsimile apparatus and an information processing apparatus are connected with one another through connecting portions over wires or by radio in a facsimile system. The facsimile apparatus includes a power supply instructing portion which outputs a power supply instruction signal through the connecting portions, the power supply instruction signal instructing whether power supply is on in all the portions of the information processing apparatus or power supply is on only in certain portions of the information processing apparatus, the certain portions being used for receiving the power supply instruction signal from the facsimile apparatus and causing power supply to be on in all the portions of the information processing apparatus. The information processing apparatus includes a power supply controlling portion which causes power supply to be on in all the portions of the information processing apparatus or power supply to be on only in the certain portions of the information processing apparatus, according to the power supply instruction signal from the power supply instructing portion.

Facsimile system

An information processing apparatus has a base portion connected to a main apparatus. An operation panel comprises one or more panel units fittable on the base portion in such a way that the panel units can change direction. The operation panel units each include a lower part fittable in the base portion, an upper part including an input device and/or a display device, and a rotating part permitting rotation of the panel units to change direction of the panel units on the base portion. The rotating part is slidable on the base portion between a home position of the panel units and a direction changing position of the panel units. A holder holds and releases each panel unit to fix the panel unit in the home position.

An electrophotographic apparatus capable of forming a high quality image by a contact type developing system using a photoconductive belt and a developing roller. The belt has a tubular configuration. A single friction roller is made of rubber and received in the tubular belt to drive it in a rotary motion. The friction roller has an outside diameter smaller than the inside diameter of the belt to provide the belt with a slack. The developing roller contacts the slack of the belt and, therefore, contacts the belt over a sufficient nip width.
