Problems solved by technology

However, after the sensor is installed to sense the potential on the surface of the photosensitive element, the voltage output of the charging device is adjusted. This method must be completed with a high-precision sensor, which will inevitably increase the production cost.
[0006] Therefore, it is necessary to propose a method to improve the problem of uneven image display in the printing process

Embodiment Construction

[0022] figure 2 is a schematic diagram of a printing apparatus according to an embodiment of the present invention. The printing device 200 has a photosensitive element 210, a rotating roller set 220, a charging device 230, an exposure device 240, and two developing elements 250a and 250b. The photosensitive element 210 is sleeved on the rotating roller set 220 , and is cyclically rotated by the rotating roller set 220 in the direction indicated by the arrow. Wherein, the photosensitive element 210 can be a photosensitive belt or a photosensitive drum, and the charging device 230 can be a corotron or a scorotron. In addition, the exposure device can also be a laser (Laser) device or a light-emitting diode (LED) device, and the number of developing elements can be configured according to requirements, for example, four are configured.

Abstract

A develop method comprises charging a light sensitive component via a charger to provide a surface potential on the light sensitive component, developing the light sensitive component via an exposuredevice to form a latent image on the light sensitive component, developing the latent image via a develop component and holding the surface potential on the light sensitive component when the chargercharges the light sensitive component agent to expose and develop again.

Description

technical field [0001] The invention relates to a developing method in a printing device, and in particular to a developing method which can improve the printing quality of the printing device. Background technique [0002] The electrophotographic printing device performs image printing by means of electrophotographic (ElectroPhotoGraphy, EPG). Photoelectric imaging generally has several steps, including charging, exposure, developing, transferring, and fusing. [0003] When the printing device intends to print images, firstly, a high-voltage corona charger is used to fill the surface of a photoconductor with negative charges, which is the charging step. However, generally in a one-pass printing device, multiple charging devices are used to complete the charging step of the image of the same image unit (such as a printed page). This configuration will cause the volume of the printing device to become larger, so The production cost consumed increases, and the amount of ozon...
