Abstract

PURPOSE:To transfer efficiently a distinct image, by tacking a toner image formed on an electrophotographic photosensitive drum to a transfer base material whose surface has a peeling property, forming a transfer layer being a mirror image of an original, and heating and pressing this transfer layer to a regular transfer material. CONSTITUTION:An image which develops a image of an original A on a photosensitive drum 1 of an electrophotographic photoreceptor 1 by a toner 24 is transferred by use of a tacking corona device 6, onto a transfer base material 20 having a peeling layer 23 which applies a peeling agent such as silicon resin, etc. on a supporting body 22 such as paper, a plastic sheet, etc., is tacked by a heat drum of a tacking machine 10, and a transfer layer 25 having an inverted image of the original A is tacked on the peeling layer. Subsequently, this transfer base material 20 is superposed with the transfer layer 25 on the surface of a regular transfer material, is transferred by use of a heating press plate, a heating roll, etc., and thereafter, the supporting body 22 is peeled off together with the peeling layer 23, by which a transfer material is obtained. In this way, a distinct picture can be transferred efficiently and at a low cost.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a transfer material and an apparatus for manufacturing the same.

In the present invention, a photoconductor is electrostatically charged with a charger, and an optical image corresponding to the document is projected onto the surface of the paper by an exposure device to discharge the charge and create an electrostatic latent image. A toner is applied to the surface of the photoconductor on which a latent image has been formed, and then it is developed and peeled off.
A device characterized in that an nfcrIMIi8I layer visualized by a photoconductor is temporarily adhered to the peeling layer @ surface of a transfer substrate on which a peeling layer is formed. As shown in FIG. 9, an attempt is made to reduce costs by providing a transfer material that can transfer clear image lines.

FIG. 1 shows a schematic vertical W of a manufacturing apparatus according to an original embodiment of the present invention.
FIG. 2 is a cross-sectional view of the transfer base material.

A drum-shaped photoreceptor and a conductive support (2
) and a photoconductive insulating layer (3).

As the conductive support (2), a metal conductor such as tin, copper, or aluminum, hygroscopic paper, or the like is used. Photoconductive insulation layer +31
ri, which directly holds a charge, and may be made of a forming material that has high resistance and can hold a charge, such as unquality selenium, ZnO + resin, ZnCd50 resin, etc.
The photoconductive layer is formed from a highly photoconductive material such as S, CdSe, or crystalline Se, and the surface thereof is transparent and can hold a static charge, such as fluorocarbon resin or polycarbonate l! f fat,
An insulating layer made of polyethylene resin may be formed.

Then, a charging device (4) such as a corona discharger, a developing device t53, a temporary corona device (
6), a cleaning device (7) is provided.

In the developing device 11i1, a wooden collar is provided on a belt (9) stretched over a pair of rollers (8), and the belt (9) is run endlessly to transfer the powdered toner collected at the bottom of the belt to the photoreceptor (tl).
Although this developing device applies cascade coating to the peripheral wall of the developer, it may also be a device that uses other developing methods, such as a magnetic brush developing method. The cleaning device (7) is a rotating brush-shaped cleaning device that removes the powder toner remaining on the photoreceptor +13 after temporary adhesion is completed.

Further, a temporary attachment device consisting of a heater or the like is provided at a position slightly apart from the peripheral wall of the photoconductor fl).

(No. 1 is the main body of the manufacturing equipment.) On the top of this main body (11) is a driving machine. ll (not shown)K! #) A document mounting table is provided that can freely move back and forth. The document mounting table 9 is composed of a cover a which can be opened and closed, and a glass stand to which the end of the cover is pivotally attached, and the glass stand faces the end of the exposure device.

Exposure device (151, lamp t+a+, lens (Iη,
It is constructed by appropriately arranging reflective mirrors 181 and the like.

The light emitted from the lamp and reflected by the document mounting table α is reflected by a reflecting mirror and is irradiated onto the photoreceptor +1).

Second, the edge of the transfer substrate placed on the feeding device installed in the main body (lo) is moved along a conveyance path formed by a conveyance belt (not shown), conveyance rollers (products), etc. It is designed to be transported.

Here, to explain the transfer base ■, paper, synthetic paper,
A release layer coated with a release agent such as silicone resin is formed on a support material (b) made of a plastic sheet or the like. However, if a releasable plastic sheet or the like is used as the transfer base material, the surface thereof becomes a releasable layer, so there is no need to form a releasant layer coated with a releasant.

Next, the operation of the above dormitory embodiment will be explained.

The transfer substrates mh are placed on a feeding device 111 so as to be fed one by one.

Then, the electrostatic charger (4) electrostatically charges the body (1). This polarity may be either positive or negative. The original (A) is placed face down on the glass stand of the original placing stand, and is covered with a lid. Then, at the same time as moving the document placing table in a predetermined movement direction (in the direction of the coming line arrow), the photoconductor i1) is rotated T'S and the lamp haze is turned on.
An image consisting of the same image lines as the original, that is, non-inverted image lines, is projected onto the charged surface of the photoreceptor +1+.

Then, due to the photoconductivity of the photoreceptor (1), the surface potential will rapidly attenuate, and an electrostatic latent image identical to that of the original (A) will be formed.

Then, powder toner is applied from a developing device (6) to the electrostatic latent image formed by the exposure device t+51;
Powder toner adheres to the electrostatic latent image to form a visible image.

When the original table (1) has moved to the end and a visible image has been formed on the photoreceptor (1), the document table α4 returns to its original position and the exposure device 9@O lamp α@ is turned off. And photoreceptor +1)! '; m, the starting end of the image is placed opposite the temporary corona device I6), and the end of the transfer substrate is transported by the feeding device - and comes into contact with the photoreceptor +1), and the opposite charge to the powder toner is applied to the temporary corona device. By adding in the device (6),
The powder toner 1241 adheres to the surface of the release layer opening of the transfer base material, and electrostatic temporary adhesion is performed.

Next, the end of the transfer substrate moves along the surface of the thermal drum of the temporary fixing device +101, which has a heater etc. therein, and moves to the third side.
As shown in the figure, the end of the transfer layer, which is a mirror image of the original (A), is temporarily attached to the original (A).

10,000, After the transfer is performed, the photoreceptor 11] is cleaned by the cleaning device (7
), the powdered toner (fl) remaining on the surface of the photoreceptor (fl) is rubbed by a rotating brush with bristles planted on its periphery.
goods), cleaned and prepared to go into the first process of next repeated use.

In this way, on the surface of the release layer (c) of the transfer base material, an inverted image of the original (A), that is, a mirror image, is formed by the powder toner (c).

An example of a method for transferring using the transfer material manufactured as described above is to polymerize the four side surfaces of the transfer layer of the transfer material on the surface of the transfer material, and then use a heated press plate, a heated roll, etc. is used to heat and press the transfer material, transfer the transfer layer □□□ onto the material to be transferred, and then peel off the end of the support material with a peeling layer (c) to perform the transfer.

The present invention provides a transfer material having the above-described structure, which can be manufactured using a relatively simple device, which improves the efficiency and cost of manufacturing the transfer material, and which can transfer clear image lines. Obtainable.
