Abstract

PURPOSE:To offer an excellent print without blurring of transfer by operating a forced electrostatic force to restrict a toner image transferred from a recording body on recording paper to prevent the disturbance of the toner image because of the effect of an external absorbing force. CONSTITUTION:A conductive belt 17 is wound on a transfer roller 13 and a belt 17 is formed as a carrying belt of recording paper 12. The belt 17 is moved by forming the type of material of a roller 18 as a rubber having a large frictional resistance and turning the roller 18. Further, in using cut paper as the recording paper 12, a transfer roller 13 is moved up and down and the conductive belt 17 is pressed onto the recording paper 12 only at the transfer. Through the constitution above, a voltage is applied to the transfer roller 13, the toner image is transferred onto the recording paper 12 by the electric field then the recording paper 12 is carried by the conductive belt 17. Since the voltage is applied to the belt 17 in this case, an electrostatic force is exerted between the transferred toner image and the said belt via the recording paper and the toner image is restricted on the recording paper 12.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Technical Field of the Invention The present invention relates to an image signal recording device used in facsimiles, etc., and particularly relates to a recording electrode and a magnetic toner developing device via an insulating recording medium. The present invention relates to a recording method in which a toner image is formed on an insulating recording medium and transferred onto a recording paper at the same time as an image signal is applied.

(B) Background of the Technology As the amount of information increases, it is required to process this information in large quantities and at high speed using electronic computers.

It is necessary to output the results of processing using the electronic computer number as output information in printed format, and electrophotographic devices and electrostatic recording devices are widely used as devices that can print in large quantities at high speed. .

(C) Prior Art and Problems Here, the configuration of the printing section of the recording apparatus and the outline of the entire printing process will be explained.

FIG. 1 shows the configuration of the printing section, which is a multi-stylus electrode in which one recording electrode and electrode needles 2 from a plurality of groups are arranged in a line. An insulating recording body 3 made of a dielectric film is brought into contact with this recording electrode 1. On the other hand, there is a rotating magnetic roller 5 inside the fixed cylindrical sleeve 4.
A magnetic toner developing device 6 is installed at a position facing the recording electrode 1 with an insulating recording member 3 interposed therebetween. A plurality of segmented counter electrodes 7 are mounted on the cylindrical sleeve 4.
Place them close together. The means for recording is a 1% magnetic recording electrode needle 2 that transfers magnetic toner to the outer periphery of the cylindrical sleeve 4.
Compatible with 1 image signal! By selectively applying a voltage of opposite polarity to the voltage applied to the recording electrode needle 2 to the counter electrode 7I, the magnetic toner carried onto the selected segment is charged, and the following hand? This is a method of attaching magnetic toner to the edge recording medium 3 to form a toner image.

FIG. 2 shows the configuration of the recording device, and the HC recording process will be explained using this figure. PP+I4: NRL recording body 3 dielectric films are made into a belt and cylinder 8.9
, 10t, thereby rotating at a constant speed.

The tip of the recording electrode 1 is placed in contact with the inner side of the belt-shaped insulating recording body 3. In addition, a magnetic toner imager 6 having the aforementioned counter electrode 7 on the surface of the cylindrical sleeve 4 is used for recording M.
Install it opposite pole 1.

After forming a toner image on the insulating recording medium 3 by the means described in FIG.
The recording paper 11 is conveyed in parallel, and the toner image is transferred from the side to the F recording paper 11 using a transfer roller 12. After this, the transferred image on the recording paper 11 is fixed to the recording paper 11 by a pressure fixing device 13. On the other hand, the insulating recording body 3 is further rotated, and a corona charge remover 14 is used at the grounded part of the cylinder 8 to erase the charge of the magnetic toner remaining on the insulating recording body 3 and insulate it. When the insulating recording material 3 is further rotated and conveyed to the printing section, the remaining magnetic toner is collected by the magnetic force of the magnetic roller 5 of the magnetic toner developing device 6. Recording 3- By repeating the recording process of Wi''
Continuous image output can be obtained on recording paper.

Since this recording apparatus can simultaneously perform the latent image formation process based on the r recording electrode number and the development process using the imager, the apparatus configuration is simple, compact, and inexpensive.

Further, since magnetic toner is used, untransferred toner can be collected from the developing machine and reused after cleaning, so maintenance is easy and the cost of consumables is low.

The problems caused by the conventional transfer mechanism ζ in the above-mentioned recording apparatus will be explained. FIG. 3 shows an enlarged view of the transfer section.

Incidentally, FIG. 3 is an explanatory diagram of the roller transfer ζ sticking.

This recording method applies the discharge phenomenon, and forms a concavo-convex layer on the recording pot body 3ζ to generate discharge, and creates a gap between the bottle electrode and the recording body with this concave-convex layer, and creates an optimal discharge. Holding the gap. Therefore, after the toner image is transferred to the recording paper, the charge on the bottle electrode passes through the gap and directly
It is difficult to move from the ground plane to the 9th floor.

4- On the other hand, since the transferred toner image has no attractive force to be restrained by the recording paper 12, it is easily affected by external electrostatic force.

Therefore, due to slight fluctuations in the conveyance path of the recording paper 12, as shown in FIG. 3, the transferred toner image is affected by the latent image charge, causing the toner image to scatter. There was a problem in that the resolution decreased due to the transfer.

0 OBJECTS OF THE INVENTION The present invention has been made to solve this problem, and in order to restrain the toner image transferred from the recording medium onto the recording paper, the external attractive force is reduced by applying a forced fishing force and an electrostatic force. To provide a good print without transfer blur by suppressing the disturbance of a toner image caused by the influence.

■Structure of the Invention In order to achieve this object, the present invention has a recording electrode in which a plurality of electrodes are arranged and emitted by sandwiching an insulating recording body, and a magnetic toner developing section, and a magnetic toner developing section. The toner developing section is
By selectively applying voltages of opposite polarity between the recording electrode and the counter electrode, which are opposed to each other across the plurality of recording electrodes, magnetic toner is transferred to the counter electrode. In a recording method in which a toner image formed on an insulating recording medium is deposited on the recording medium and then transferred to a recording paper, a conductive belt is used as a conveying means for the recording paper, and the recording P ,? During the transfer, the toner image is transferred to one side of the recording paper using the electrostatic force caused by the voltage applied to the belt. Due to the electrostatic force acting between the electric charge of the transferred toner image and the voltage applied to the four-electroconductive belt disposed on the other side of the recording paper, the toner image is transferred to the insulating recording medium. This is achieved by providing a distribution method that is characterized by retaining the top.
