Abstract

PURPOSE:To obtain small-sized and easy-to-handle electrophotographic printer by providing a photosensitive plate, a carrying means, an exposing means, a developing means, and a transferring means. CONSTITUTION:When one printing ends, the photosensitive plate 10 moves to a position PA by rack-and-pinions. During the movement, a photoconductive layer on the photosensitive plate changes into an electric conductor, loses charges and power to adsorb toner liquid by the light of a destaticizing lamp 34. The toner liquid is removed by a cleaner 32. Next, the photosensitive plate 10 moves to a position PB. During the movement, its surface is electrified negatively by a corona discharger 26, the irradiated part of an LED 28 loses charges, and an electrostatic latent image is recorded. When the photosensitive plate passes through a developing unit 30, it comes into contact with a magnetic roll and positively electrified toner is adsorbed to negative charges on it to develop the image. A transferring device 24 electrifies a sheet 22, which is pressed onto the photosensitive plate 10, and transferred a toner image at the position PB. When one transferring ends, the sheet 22 is carried to a heat roller 25 and the photosensitive plate 10 is carried to the position PA. The exposing means, etc., is miniaturized because they require merely the width of the photosensitive plate.

[Prior Art] In the electrophotographic recording method, printed information is recorded as an electrostatic latent image on a photoreceptor, and a pigment such as toner (developer) is attached to this latent image to form a visible image (visible image). This method of transferring visible images onto paper is generally used in copying machines, but in recent years this electrophotographic method has also been adopted in printers.

First, the equipment is expensive. In particular, when a laser beam method is used as an exposure means to irradiate a charged photosensitive drum with light to form a latent image, it is necessary to control the laser beam with high precision, but the laser optical system and mechanism for this are complex. Therefore, the exposure means is expensive. Further, even if an LED (light emitting diode) array method is adopted as the exposure means, in the conventional method, the LED array has the size of the paper width, and within that width there are 1000 to 1000 dots corresponding to the number of recording dots. Since it constitutes a large number of LEDs, such as 2000, it becomes expensive. Furthermore, the price of photosensitive drums is high.

Further, regarding the exposure means, in the laser beam method, the laser optical system and the mechanism section occupy a large space, and in the LED array method, the LED array has the width of the paper, so it is large in size.

[Operation] During the movement of the photosensitive plate from the forward movement position to the backward movement position, the exposure means irradiates light onto the photosensitive plate to record an electrostatic latent image corresponding to printing information. The latent image formed on the photosensitive plate is visualized by applying toner to it by a developing means.
