It is enough to be preferably uniformly mixed with phthalocyanine-like compound and resinae mixture, while easy to follow-up coating and matrix.
S3, coating；
The second mixture is injected in matrix surface using membrane formation process is atomized, while phase is sprayed in the opposite side of matrix surface
Synthermal nitrogen, prevents matrix surface from causing matrix to deform due to heated different during coating, then causes to feel
The electric conductivity of light drum reduces.Meanwhile the second mixture largely and can be coated on by matrix table using atomization membrane formation process
Face.
Matrix is then carried out to appropriate cooling so that the temperature of matrix surface is at 150-180 DEG C, at this time, the second mixing
Thing is combined with matrix, is then coated on the first mixture and is coated with the matrix of the second mixture, the first mixture is again
It can be combined with matrix, while will not change because of temperature excessive and cause matrix to deform.Meanwhile the photosensitive drums only have two layers
Photoconductive layer, and the two layers of light guides layer can realize the optical conductivity that multilayer photoconductive layer could be realized in the prior art, or even its light guide
Rate can also be lifted further, and the endurance of light-guide material, wear-resisting property are also obviously improved.Meanwhile the structure of photosensitive drums
It is simplified, lifts the cooperation between light-guide material and matrix, prevent from being bonded excessive light-guide material on matrix, and causes light guide material
The mating reaction of material and matrix reduces.
