Benefits of technology

This patented technology describes an improved method for making electronic devices with multiple layers that are sensitive enough to produce images on both positive (positive) and negative surfaces without being affected during printing processes. It also allows for easy replacement of certain components within one device while maintaining its functionality. Overall, this new design makes producing multi-functional imagers easier and more efficient than current methods.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the performance of organic photoreceptors that have been developed at present time due to their limited compatibility with other components like developers. Specifically, conventional methods involve multiple steps involving different layers, leading to poor quality images being produced.

Abstract

The invention relates to an electronegative single-layer organic photoconductor drum and a preparation method thereof, and belongs to the technical field of organic photoconductor drums. The electronegative single-layer organic photoconductor drum has the advantages that TPD-FCN is used as an electron transmission material, S-100 is used as a cavity transmission material, and TPD-FCN and S-100 have the approximate absolute values of oxidation-reduction potentials, and equivalent absolute values of electron/cavity transfer rates, so that the problems of low sensitivity, light exposure and high residue are solved when the single-layer functional composite organic photoconductor drum is applied to an electronegative laser printer; by adjusting the contents of components in a coating liquid, the photoelectric property of the prepared electronegative single-layer organic photoconductor drum reaches or approaches to the level of the multi-layer functional separation type electronegative organic photoconductor drum; compared with the multi-layer functional separation type electronegative organic photoconductor drum, the preparation process is simple, the production efficiency is high, the production cost is low, and the like.
