摘要： A thermal transfer printing method includes the steps of overlapping a surface of a printing layer of an intermediate transfer member having the printing layer on a base member with an ink sheet. Thermal transfer printing from the ink sheet to the printing layer is effected, subsequently overlapping the intermediate transfer member with an image receiver for transfer of the printing layer onto the image receiver. Thereafter, the printing layer is fixed on the image receiver by causing the printing layer to penetrate into the image receiver through direct application of pressure and heat to the printing layer on the image receiver. A printing apparatus is employed for effecting the thermal transfer printing method.

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： An electromagnetic induced heating roller comprises a core member, an elastic layer, induction heating layer, and a mold release layer in this order from inside to outside. Further, a magnetic shield layer for preventing a magnetic flux from penetrating into the core member is interposed between the induction heating layer and the core member. The production of an alternating magnetic field from a magnetic field generating device, a leakage flux having penetrated through the induction heating layer is trapped by the magnetic shield layer. As a result, most of the impressed alternating magnetic flux is consumed for heating the heating layer, resulting in an improvement in the heating efficiency. A trouble is prevented which is generated by heating the bearing of the core member.

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.

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.
