消費してしまう欠点がある。Conventional electrophotographic printers create ml images by allowing exposure to be turned on and off for all dots printed. [Problems to be Solved by the Invention] - The conventional electrophotographic printer mentioned above is capable of turning on and off the exposure of the dots to be printed.2. b. All the dots forming the K-shape are exposed, toner adheres to all the exposed dots, and the toner is consumed even in the case of trial printing.

〔実施例〕
次に本発明について図面を参照して説明する。During exposure, the electrophotographic printer of the present invention turns on only the odd-numbered dots in the dot row for the first line.
It is possible to turn off, and all even numbered dots are exposed as off, and for the second line, only the even numbered dots in the dot row are on.
It has a mode in which all odd-numbered dots are exposed as off-0T, and the above process is repeated from the next line to create a latent image. [Example] Next, the present invention will be described with reference to the drawings.

For the line, only the even-numbered dots in the dot row can be turned on or off, and all the odd-numbered dots are exposed as off.
From the next line onwards, by repeating the above steps to improve the latent image, the image will be much more distorted than if the latent image was created by allowing all the tots in the line's dot row to be turned on and off. It is possible to reduce the number of exposed dots by about half without reducing toner consumption.
