Abstract

PURPOSE:To move toner particles from an image carrier to a transfer material and to separate the transfer material where the toner particles are moved from the image carrier by applying a corona ion stream which has oscillating components and is asymmetrical about the moving direction of the transfer material to the back surface of the transfer material. CONSTITUTION:The corona ion stream of variable strength is applied to the transfer material P at the entry side of the transfer material. Consequently, even when an AC voltage applied to a discharging wire 2 is increased, none of charges of the corona ion flow is applied to toner 4 on the image carrier 5 and no toner 4 is attracted by the transfer material P in an area B preceding a transfer area, so that the toner 4 on the image carrier 5 moves to the transfer material P without causing image disorder in the transfer area A. Therefore, the AC voltage applied to the discharging wire 2 is so stable, that high transfer efficiency is obtained even if the charge holding capability of the transfer material P deteriorates.

The transfer separation method in the conventional recording apparatus described above uses an adhesive material for the transfer material and presses the transfer material against the image carrier to transfer the toner image from the image carrier to the transfer material. Then, the transfer material is separated from the image carrier using conveyance gripping claws or separation claws, or the donor charge on the image carrier is applied to the transfer material from the back surface using an electrode roller or a corona discharger. And the opposite pole! A method is known in which a toner image on an image carrier is transferred to a transfer material by applying a voltage of 2, and then the transfer material is separated by means similar to those described above or by a corona discharger for separation. Among these methods, the method of transferring and separating using a corona discharger does not require the use of special transfer materials with adhesive properties, and is not used to causing toner image collapse as in adhesive transfer or transfer using an electrode roller. It is widely used because it provides a relatively high transfer efficiency and is less likely to damage the image carrier, unlike separation using one-separation claws, and the device is simple. The conventional transfer separation method using this corona discharger, as shown in Fig. 1, uses separate corona dischargers for transfer and separation/separation, respectively. Apply a DC voltage to the discharge wire of the electrical appliance, apply a DC voltage to the cover plate (J) or a scorotron grid (not shown), or generate a DC corona ion flow such as that obtained by grounding the cover plate (J). Although this method has excellent effects as mentioned above, if the charge retention property of the transfer material P decreases due to factors such as 11 degrees, the transfer efficiency will decrease. However, if the direct current corona ion flow is strengthened to increase the transfer efficiency, the transfer area will be charged to the same charge as the flow, and the toner particles will be repelled from the transfer material P by the rounding, which will actually reduce the transfer efficiency. If the film falls, it may cause image disturbance and be smeared, and it may also be attracted by the strongly charged transfer material P, causing it to be transferred before it is transferred. For some reason, image disturbance may occur, so the discharge conditions of the corona discharger I are within an extremely narrow range I! The problem is that it is limited to

In the embodiment shown in FIG. 1, the corona discharger l is provided with two discharge wires 2', and the discharge wire on the side where the transfer material P enters is connected to a rectifying element 4 with 10 fiz
An AC voltage of -100 kll & 100 kv is applied to the discharge wire on the output side of the transfer material P! Since the same AC voltage is directly applied to both, the cover plate 3 is grounded. Therefore, °−′: 1−lower discharge @/ is,
On the entrance side of the transfer material P, that is, in the transfer area ゛・mu, a discharge wire applies a corona ion flow whose intensity changes with opposite polarity to the charge of the toner on the image carrier j to the back surface of the transfer material P, and transfers. On the exit side of the material P, a discharge wire applies a corona ion flow whose polarity changes from positive to negative to the back surface of the transfer material P. In this way, by applying a corona ion flow whose intensity changes to the transfer material PK on the entrance side of the transfer material P, the discharge wire J
Even if the AC voltage applied to K is increased, the charge of the corona ion flow remains on the image carrier! The upper toner IK is no longer injected, and the transfer material P no longer attracts some of the toner in the pre-transfer area B, and the image carrier! The above toner is used for easy transfer as it causes image disturbance in the transfer area.
Move to P. Therefore, since it is possible to increase the AC voltage applied to the radiation wire JK, stable high transfer efficiency can be obtained even if the charge retention property of the transfer material P is reduced. In addition, by applying a corona ion flow whose positive and negative changes are applied to the transfer material PK at the exit side of the transfer material P, the alternating current voltage applied to the discharge wire can also be increased, stably and reliably. As a result, the transfer material P can be easily separated from the image carrier S without disturbing the transferred toner image.

In the embodiment shown in FIG. 3, the same alternating current voltage 1 as in FIG. is separated into a cover plate 3',
The cover plate 3 on the entrance side is directly grounded, and the cover plate r on the exit side has an image carrier! A DC voltage of opposite polarity to the charge on the toner above is applied. As a result, the discharge wire applies to the transfer material P a corona ion flow whose intensity changes, rich in ions of opposite polarity to the charge of the toner particles, to the transfer material P on the entrance side of the transfer material P, that is, in the transfer area, and In other words, in the separation area C, a corona ion flow rich in ions that eliminates the charge on the transfer material PO is applied to the transfer material P. Therefore, in the embodiment shown in FIG. 3, as in the embodiment shown in FIG. 2, images can be transferred with stable and high transfer efficiency without disturbance, and separation can be easily performed. Konishi Roku Photo Industry Co., Ltd. Copy @U-BixVK The result of implementing the example shown in Fig. 3 shows that the transfer efficiency is as high as 0% to 0%, which is compared to the conventional copying machine U-BixVK as described above. BixV showed an average improvement of 10% in transfer efficiency compared to Yuru. In the example of FIG. 3, it goes without saying that applying a DC voltage to the cover plate J can also be done by using an AC rectifier, a resistor, a zener diode, etc.

As mentioned above, one Tl! 4 provides excellent transfer separation because (1) by changing the corona ion flow, the transfer material is not charged more than necessary, the applied voltage is stabilized, and the corona ion flow is (21) The force generated by a changing ion flow is more effective than the force generated by a constant direct current ion flow to transfer the toner from the image carrier to the transfer material. Although this overlaps with (3)/, the average voltage applied to the transfer material decreases due to the changing ion flow (4), so the reverse charging of the toner in the transfer area and the transfer of some toner in the previous section, etc. (4)
) The separation area is close to the transfer area, and the voltage of the transfer material changes continuously in a narrow area, which also prevents the toner from being charged in the opposite direction, resulting in image disturbance and reduced transfer efficiency4. This is thought to be due to reasons such as the loss of .
