Abstract

PURPOSE:To improve ground contamination and unevenness of a picture by inclining by a prescribed angle a joint part of a belt-like electrostatic recording body belt without making it vertical against the end edge. CONSTITUTION:A joint 10A of an electrostatic recording body belt 5A is inclined by an angle theta against the belt end edge. When the belt 5A is carried like a belt 5, and the joint 10A passes through under a blade of a cleaner 1, it does not occur that all of the joint 10A collides with the blade 1. In this case, since a collision area is reduced, a shock given to the blade 1 is reduced, and accordingly, damage of the blade is prevented. Also, it is reduced that the blade 1 is floated or separated from the belt 5A due to a shock, therefore, the toner removing effect is equalized and raised.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrostatic recording belt K, and includes lI? The present invention relates to an electrostatic recording belt used in a temporary copying electrostatic recording device.

More specifically, the present invention relates to the arrangement of the dark blue stitches or joints of an endless electrostatic recording belt.

FIG. 1 schematically shows the configuration of a transfer type static recording device 1'L. The rollers 7A, 7B, 7C&i-, L-] are rotated in the direction of arrow Q.

The multi-needle electrode 2 is in contact with the recording body bell 15 over the entire width vi1, and 4) or -j; 1
It is arranged to hold 1. 7. As is well known, by supplying pixel signals to the bottom and bottom electrodes, recording r4
, electrostatic latent ridges are formed on the surface of the belt 50. 1 developing machine 3
is multi-needle 'r[i' placed downstream 11t1 of pole 2 (and 6
i Use an air brush etc. to keep the conveying surface of the recording belt 5 static.
Apply toner to the potential latent image area and perform development.1.
6 shows the toner image visualized as described above.

Take the recording paper 4 one by one from the appropriate tray 9, arrow El]R
As shown in , it is supplied to the transfer row 28 .

At the position of the transfer roller 8, the recording paper 4 is placed on the recording belt 5.
The toner image 6 is pressed onto the recording paper 4 and is transferred onto the recording paper 4.Then, the toner image on the recording paper 4 is, for example, thermally fixed.9After being transferred, it remains on the recording belt 5. The toner contained therein is removed by a cleaner 1.

Therefore, the recording belt 5 circulates under the multi-needle roller 11 and the outer pole 2 in a clean state.

In the above-mentioned wide transfer type electrostatic recording device (for example, the recording belt 51, which has conventionally been used in a general button, has a belt-like belt as shown in the perspective view 71 in FIG. The seam or joint was made perpendicular to the belt edge.11 In this way, a belt-shaped static recording belt When joining both ends of 50 to make an endless, it is extremely difficult to make the joint or seam the same as other parts (aligning the surfaces on the same plane) 6) 1#, and: l
'j': It is unavoidable to create unevenness at the joint1
On the other hand, mechanical fur brushes, cloth, or grades are known as cleaners to completely remove tonneau. It is desirable to use a blade for i-ra.1 However, as mentioned above, the conventional hc recorder belt 5,
The joint part is at a right angle tS' to the edge of the recording belt 5.
Therefore, when a blade is used as the cleaner 1, an impact is applied to the cleaner due to the unevenness of the joint part of the belt, and as a result, (1) the blade rises from the recording belt 5 and becomes stiff. (2) The blade may become deformed or damaged, or (2) the blade may become deformed or damaged.

For this reason, in the past, it has been thought that 1/1/-density cannot be used in such electrostatic recording belts, and 7I-Puji/cloth has been exclusively used as a cleaner. However, fur brushes and cloths do not remove toner enough, and a countermeasure is needed.

An object of the present invention is to provide an entire electrostatic recording belt having a single 47F structure, which is capable of using a blade.2. .

Is this invention intended to fulfill the purpose of No. 1311? (In addition, when joining both ends of a belt-shaped electrostatic recording belt to make it endless, the joint part is not perpendicular to the edge of the recording belt, but is inclined at a predetermined angle. ′:)
The present invention will now be described in detail with reference to the drawings. FIG. 4 is an F view of an electrostatic nCC bowl belt according to an embodiment of the present invention, and FIG. 5 is a developed view thereof.

Figure 4 1]・Call! As is clear from Fig. 85, in the static 'rK recording belt 5A of the present invention, the seam 1OA is tilted by an angle θ degree with respect to a line perpendicular to the edge of the belt. Because of the configuration: 'J'+jl, the recording belt 5A is conveyed to the strand of the recording belt 5 at 1 in FIG. When passing through the joint, the entire joint 10A does not collide with the cleaner (blade) 1 at the same time.3 In other words, compared to the previous example, the collision 1111 is reduced, so the cleaner (blade 1) ) 1 is reduced and therefore damage to the blade is also prevented. In addition, the degree to which the cleaner (blade) 1 floats up or separates from the electrostatic recording material PEL 5A due to impact is sufficiently reduced, so that the toner removal effect is uniformed and improved6. In the experiment, in the case of an electrostatic recording belt with a width (W in No. 57-1) of 300 strips, the distance between the foot of the perpendicular line drawn from one end of the joint (seam) and the other end of the joint (seam) Ran ('−
Particularly good results were obtained by applying (L in Figure 55) approximately 15 or more times.
Distance length of iii note <-i report, /' j,
Although the influence on the recording medium is reduced, on the other hand, the area that cannot be used for image formation is increased, and the effective length of the recording body (belt) is shortened, so there is a natural limit to the length.

It is clear from the explanation that the VC of the present invention can completely improve background smudges and unevenness in images.
