摘要： A resistive ribbon thermal transfer printing apparatus produces two kinds of electric pulses for selectively energizing recording electrodes of a printing head according to a data to be printed. A first electric pulse (normal pulse) is applied to a recording electrode which is to be energized and is disposed between two recording electrodes which are to be energized. A second electric pulse (specific pulse) is smaller in energy than the normal pulse and is applied to a recording electrode which is to be energized and is not disposed between two recording electrodes which are to be energized. This selective application of the two kinds of pulses allows the size of the printed dots to become uniform.

摘要： An image read apparatus for reading an image on a document which includes a reciprocatively movable document placing plate for placing thereon the document, a document placing plate driving mechanism for driving the document placing plate and an image reader for reading the image information on the document. The document placing plate is movable reciprocatively between a first position where the document placing plate is housed completely in the image read apparatus and a second position where the document placing plate projects outwardly from the image read apparatus to thereby enable the document to be placed thereon. The image read apparatus sequentially reads the image information on the document between each sequential movement of the document placing plate from the second position to the first position. Preferably, a document holding member such as a flexible sheet or an endless belt is provided for pressing the document onto the document placing plate within the image read apparatus.

摘要： The average friction factor between the contact surfaces of a drive roller and an intermediate transfer belt is set to not more than 0.45 and not less than 0.1, and before the primary transfer of the toner image of the last color is finished, a cleaning blade is separated from or comes into contact with the intermediate transfer belt with the drive roller as a backup member. The peripheral length of a photoconductor is greater by not more than 10% than the value obtained by dividing the length on a transfer member necessary for a predetermined image length by an integer n which is not less than 3 and not more than 9, and the ratio between the numbers of rotations of the transfer member and the photoconductor is 1:n.

The belt unit is detachably attachable to the body with the opposed roller on the operator's side. The tangential line of the opposed roller is substantially vertical at a secondary transfer position. The cleaner roller is disposed in a range enclosed by the intermediate transfer belt, the tangential line of the drive roller parallel to the common tangential line of the peripheries of the tension roller and the opposed roller, and the vertical tangential line of the secondary transfer side of the opposed roller.

The color image forming apparatus includes: a conveying apparatus for conveying the plurality of image forming units around the main axis of the cylinder between an image forming position and a waiting position by simultaneously rotating all image forming units; an exposing device 6 for exposure of the photosensitive drum of the image forming unit that is in the image forming position 10; a transfer apparatus 5, which contacts a transfer belt 50 with the photosensitive drum 30 of the image forming unit that is in the image forming position, and when the image forming unit that is in the image forming position is switched, successively transcribes the toner images of all colors formed on the photosensitive drums onto the transfer belt, superimposes the toner images of all colors and forms a colored toner image on the transfer belt; and a transfer belt driving apparatus for driving the transfer belt at a constant speed. When a second color image is formed after a first color image, the first toner image color of the second color image is formed on the transfer belt by using the image forming unit of the last color added to the first color image. The exposing device includes a light source accommodated by the inner portion of the cylinder defined by the image forming units.

摘要： A developing apparatus is arranged so that a toner container having an opening portion which can be opened or closed is engaged with a toner replenishing opening of a toner hopper so as to open the opening portion of the toner container. A rotary shaft extends through the toner container, has a toner stirring member mounted thereto, and is coupled with a driving shaft of an agitator. When rotated by the driving shaft of the agitator, the rotary shaft causes the toner in the toner container to drop into the toner hopper due to rotation of the stirring member within the toner container, which rotates simultaneously with the agitator in the hopper.
