Problems solved by technology

[0005] However, when the toner particles are transferred to the surface of the paper, because the Van der Waal’s force is very weak, the toner particles are easy to fall off from the paper
Therefore, before the toner particles fall off the paper, the toner must be fixed as soon as possible, so as not to reduce the print quality

Embodiment Construction

[0013] Please refer to Figure 1A and Figure 1B , Figure 1A A schematic diagram showing an image forming apparatus according to a preferred embodiment of the present invention, Figure 1B show Figure 1A An enlarged schematic view of the image forming apparatus. The image forming apparatus 100 includes a plurality of photosensitive units, such as four photosensitive drums 112 , 114 , 116 , 118 , an intermediate transfer unit 130 and a paper conveying unit 150 . Photosensitive drums 112, 114, 116, and 118 each carry a first toner image. The intermediate transfer member 130 contacts the photosensitive drums 112 , 114 , 116 and 118 . The first toner images are transferred from each of the photosensitive drums 112 , 114 , 116 and 118 and overprinted to the intermediate transfer element 130 to form the second toner images. The intermediate transfer member 130 rotates at a first speed Vt. The paper conveying unit 150 moves the paper 200 at a second speed Vs, and makes the pape...

Abstract

The invention relates to an image forming device comprising a plurality of light sensation units, an intermediate transfer printing unit and a paper transmission unit, wherein each light sensation unit carries a first powdered carbon image; the intermediate transfer printing unit contacts with the light sensation units so as to enable the first powdered carbon images to be respectively transferred and overprinted on the intermediate transfer printing unit to form a second powdered carbon image; the intermediate transfer printing unit rotates at a first speed; the paper transmission unit moves paper at a second speed and enables the paper to pass through the intermediate transfer printing unit so as to cause the second powdered carbon image on the intermediate transfer printing unit to be transferred and printed on each paper; and the second speed is different from the first speed.

Description

technical field [0001] The invention relates to an image forming device and an image transfer method, and in particular to an image forming device and an image transfer method of a color image. Background technique [0002] Compared with inkjet printers, laser printers provide high-speed and high-quality printing of text and images. Therefore, laser printers are widely used as computer peripheral devices for home or business use to cope with printing a large number of files. [0003] When the laser printer starts to print, first, the surface of the photoconductive drum or photoconductive belt in the laser printer is charged and exposed to form a latent image. After the photosensitive drum or photosensitive belt with a latent image contacts or approaches the charged toner (toner) processed by the development system (development system) of the laser printer, the toner will adhere to the latent image, so the latent image will be converted into a toner image. This toner image...
