[0002]

2. Description of the Related Art Conventionally, image information output from a copying machine, a printer or the like has been written with character information and image information by an image forming apparatus incorporated therein. In recent years, in particular, color output has become possible, and users have come to be able to study various output.

[0003]

However, the following demands have been made by users for such an image forming apparatus. The user uses such an image receptor as a poster or wallpaper. At that time, there was hope that the scent would be emitted from the color output image-receiving body and that the deodorizing effect could be given.

As a simple measure against this, spices have been sprinkled on the image receptor. However, it was not possible to achieve a sufficient effect because it was not possible to control the placement of the scent corresponding to the part of the image, or the addition of only the necessary part.

The present invention has been made to solve the above-mentioned problems, and provides an image forming apparatus capable of adding a scent or a deodorizing effect to a necessary portion of an image receptor. It is in.

[0006]

In order to achieve this object, the image forming apparatus of the present invention is characterized by comprising a recording section for recording a toner containing at least a fragrance or a deodorant on an image receptor.

[0007]

According to the image forming apparatus of the present invention having the above construction, the toner containing the fragrance or the deodorant is attached to an arbitrary position on the image receiving body.

Next, FIG. 2 is a diagram showing an outline of the image forming apparatus of the present invention, in which 1 is provided above the aperture electrode body 1.
A cylindrical back electrode roller 22 is rotatably disposed on a chassis (not shown) with a gap of mm, and is configured to be able to convey the support body 20 inserted into the gap. ing. Further, a toner supply device 10 is arranged below the aperture electrode body 1 along the longitudinal direction of the aperture electrode body 1, and further, a support body conveyed by the back electrode roller 22. A fixing device 26 is disposed at the destination of the movement of 20.

Next, the respective components will be described in detail. In the toner supply device 10, the toner case 11 also serving as a housing of the entire device, the microcapsule toner 100 housed in the toner case 11, and the supply are provided. It comprises a roller 12, a toner carrying roller 14, and a toner layer regulating blade 18. Here, the toner carrying roller 14 is a microcapsule toner 100.
Is carried and is conveyed toward the aperture electrode body 1, and the supply roller 12 is arranged so that the microcapsule microcapsule toner 100 is supplied to the toner carrying roller 14.
To supply.

The supply roller 12 and the toner carrying roller 14 are rotatably supported by the toner case 11 in the direction of the arrow shown in FIG. Further, the toner layer regulating blade 18
Is for adjusting the amount of the microcapsule toner 100 carried on the toner carrying roller 14 to be uniform on the roller surface and for uniformly charging the microcapsule toner 100.
Pressed to No. 4.

As shown in FIG. 3, the aperture electrode body 1 has a diameter of 1 μm on a 25 μm thick insulating sheet 2 made of polyimide.
A plurality of apertures 6 having a size of 00 μm are formed in one row, and a control electrode 4 having a thickness of 1 μm is formed above each aperture 6. As shown in FIG. 3, the aperture electrode body 1 is arranged so that the control electrode 4 faces the support body 20 and the insulating sheet 2 contacts the microcapsule toner 100 on the toner carrying roller 14 at the aperture position. It is set up.

A control voltage applying circuit 8 is connected between the control electrode 4 and the toner carrying roller 14.
The control voltage application circuit 8 is configured to apply a voltage of 0 V or +50 V to the control electrode 4 based on the image signal.

Further, a DC power supply 24 is connected between the back electrode roller 22 and the toner carrying roller 14, and this DC power supply can apply a voltage of +1 kV to the back electrode roller 22. It is like this.

Next, the operation of the image forming apparatus configured as described above will be described.

First, by rotating the toner carrying roller 14 and the supply roller 12 in the direction of the arrow shown in FIG.
0 is rubbed against the toner carrying roller 14, is negatively charged, and is carried on the toner carrying roller 14.
The carried microcapsule toner 100 is thinned and charged by the layer regulation blade 18, and then is conveyed toward the aperture electrode body 1 by the rotation of the toner carrying roller 14. Then, the toner on the toner carrying roller 14 is supplied under the aperture 6 while being rubbed by the insulating sheet 2 of the aperture electrode body 1.

Here, in accordance with the image signal, the control electrode 4 corresponding to the image portion is fed from the control voltage applying circuit 8 to +.
A voltage of 50V is applied. As a result, an electric force line from the control electrode 4 toward the toner carrying roller 14 is formed in the vicinity of the aperture 6 corresponding to the image portion due to the potential difference between the control electrode 4 and the toner carrying roller 14. As a result, the negatively charged toner receives an electrostatic force in the direction of higher electric potential, passes through the aperture 6 from the toner carrying roller 14, and is drawn out to the control electrode 4 side. The extracted microcapsule toner 100 further flies toward the support body 20 due to an electric field formed between the support body 20 and the aperture electrode body 1 due to the voltage applied to the back electrode 22, and the support body 20 is supported. 20 to form a pixel.

A voltage of 0V is applied from the control voltage application circuit 8 to the control electrode 4 corresponding to the non-image portion.
As a result, since no electric field is formed between the toner carrying roller 14 and the control electrode 4, the toner carrying roller 1
The microcapsule toner 100 on 4 does not pass through the aperture 6 because it is not subjected to electrostatic force.

Further, the support 20 is fed by one pixel in the direction perpendicular to the aperture row while one row of pixels is formed on the surface of the support 20 by the microcapsule toner 100. The support 20 is then repeated by repeating the above process.
A toner image is formed on the entire surface of the. Then, the formed toner image is fixed on the support 20 by the fixing device 26.

As described above, the microcapsule toner 100 can be attached to any position of the support 20. As a result, an aroma according to the image is generated. For example, the aroma of the flower floats from the petals of the flower, and the aroma of banana appears from the picture of the banana. As a result, even in output materials such as posters and sales promotion pamphlets, which must appeal to perception, fragrance can be added arbitrarily, and thus it can be an extremely effective expression means utilizing the sense of smell.

The present invention is not limited to the embodiments described in detail above, and various modifications can be made without departing from the spirit of the invention.

For example, in the above embodiment, the control voltage of the aperture corresponding to the non-image portion is set to 0V, but this may be a negative voltage. In this case, an image with less fogging can be obtained. Further, in the above embodiment, the aperture electrode body is used as the toner flow control means, but it is also possible to use, for example, a stitched electrode body as described in JP-A-1-503221.

Further, in this embodiment, the fragrance is included in the microcapsule toner, but if the odor absorbing substance such as activated carbon is included, the deodorizing effect can be exhibited. Further, in the present embodiment, the dye and pigment are contained to have a coloring function, however, the dye and pigment may be omitted if coloring is not required.

[0037]

As is apparent from the above description, according to the image forming apparatus of the present invention, it is possible to apply the microcapsule toner that emits an aroma to any position of the support. As a result, the fragrance corresponding to the image is emitted from the output paper,
Very effective expressions are possible.
