Problems solved by technology

However, there are still some problems with the barrier layer containing polymer materials for this photoconductor: for example, after coating the barrier layer (BL), it must be baked and cured immediately, otherwise it will contaminate the subsequent charge generation layer (CGL) coating solution, which brings certain difficulties to the composition of the process and production equipment; in addition, some coatings or coatings will also accumulate charges while stabilizing the charges, so that the residual charges will gradually increase, thereby affecting the image output quality; another On the one hand, the barrier layer (BL) after heat treatment is weakly combined with the charge generation layer (CGL) coated subsequently, thus forming a strong interface barrier, which is not conducive to the migration of charge carriers, or the formed thin film Poor charge acceptance for charging
In addition, under certain conditions, it will also cause interface light interference, which will affect the quality of the image

Description

technical field [0001] The invention relates to an information processing device or device used for copying, printing, facsimile and other functions in electrostatic imaging technology, in particular to a barrier layer of an organic photoconductor containing polymer materials. Background technique [0002] The early photoconductors used aluminum as the substrate, and the surface of the substrate was coated with a layer of inorganic photoconductive materials by vacuum coating method, such as zinc oxide (ZnO), selenium (Se), selenium tellurium alloy (SeTe), selenium tellurium arsenic alloy (SeTe :As) and other semiconductor materials to form a single-layer inorganic photoconductor. Due to the inherent disadvantages of inorganic photoconductors, such as high product toxicity, long film-forming time, high cost, and few varieties, etc., in the late 1980s, they were gradually replaced by organic photoconductors that are non-toxic, good in performance, low in cost, and diverse in v...
