Problems solved by technology
If the movement of the photoreceptor belt along the bottom side cannot be fully synchronized with the paper supply, the developed latent image transferred to the paper may be blurred, twisted, or developed unsuccessfully
Therefore, the synchronization between the image transfer unit and the paper supply is another problem of the traditional photoelectric imaging color printer.

Embodiment Construction
[0018] The photophotographic printing apparatus disclosed in the present invention has a photosensitive belt and combined components (such as a charging unit, an exposure unit, a developing unit, and a cleaning unit) configured to provide the electrophotographic printing apparatus with a small size and greatly reduce the above-mentioned conventional small size Disadvantages of model printers (such as excess toner falling back onto the photosensitive belt from a cleaning unit due to gravity).
[0019] refer to figure 1 , is a schematic side view of an electro-optical imaging printing device 100 disclosed in the present invention. This electrophotographic printing apparatus 100 at least includes a photosensitive belt 102 which has an outer surface 104, and several support members 106, 108 and 110, such as rollers, which are operatively configured to support the photosensitive belt 102 along such as figure 1 A path running in the direction of an arrow A in the middle. The elect...

Systems consistent with the present invention provide an electrophotographic printing apparatus that includes a group of developing units, a photoreceptor belt having an outer surface, and a group of support members, such as rollers operably disposed to support the movement of the photoreceptor belt along a path. The photoreceptor belt has a shape defined, at least in part, by the support members. The shape of the photoreceptor belt has at least two sides meeting at a transfer point. The first of the two sides extends at a first angle from the outer surface of the photoreceptor belt to a horizontal axis of the apparatus at the transfer point and the second of the two sides extends at a second angle from the horizontal axis to the outer surface of the photoreceptor belt such that the first and the second angles are each less than 90 DEG C. Each developing unit is disposed adjacent to the first or the second sides of the shape of the photoreceptor belt.
Description
technical field [0001] The present invention relates to photoelectric imaging technology (electrophotography), in particular to a small electrophotography color printing device. Background technique [0002] A conventional photoelectric imaging color printer has a photoreceptor drum or belt, charging units, exposing units and development units. Usually, the photosensitive drum or belt receives a uniform charge from one of the charging units, and then the charged area is exposed by one of the exposing units to form a charged pattern (that is, a latent image) corresponding to a light image in this area. ). To develop the latent image, the photosensitive drum or belt carries the latent image to one of the developing units, where the latent image is exposed to a combined charged toner which adheres to the charged portions of the latent image. If the latent image requires two or more color toners for development, the above process will be repeated. When the latent image has be...
