Such iron toner surrounded by adsorbed toner iron permanent magnets to form a similar brush-like layer of iron with carbon mixture. When passing under the surface of the drum from the magnetic brush, carbon toner negatively charged sucked the surface of the drum remains part of the positively charged to form a visible toner image. The role of the agitator is iron with carbon friction charged. The photosensitive drum surface of the electrostatic latent image "contrary to the charge polarity of the charge developing toner, drum and toner-carrying magnetic roller is close to a certain distance, the toner is attracted to or toner jump to the drum surface to form a toner image, also known as the beating developer. More orders of  green laser pointer  has been added.
Note: laser machine photosensitive drum exposed surface of the electrostatic latent image "charge was negative, toner electric charge of positive polarity. The developing unit toner transfer is completed. When the toner in the toner inside the blender uniform, the toner carried by the doped carrier permanent core adsorbed to the outer surface of the magnetic roller and magnetic roller, when toner is not obvious polarity. When carrying toner rotating magnetic roller and the tangency with the toner scraper, with which the friction, so that toner to bring a positive charge. Toner in the toner scraper and magnetic field on the surface of the magnetic roller to form a toner fog hate thin and the distribution is uniform. Toner scraper also play a role in limiting the amount of toner, the toner without adsorption too much. The performance of  green laser pointer  has been verified by the workshop.
Mentioned earlier, the residual potential of the photosensitive drum print "bottom ash", the solution is combined with the appropriate AC and DC "bias" in the magnetic roller sleeve to offset toner excessive transfer. Developing bias has two roles, and properly adjusting the developing bias, first, to prevent the "bottom ash", the second is to adjust the print density. Practical application, the print density adjustment knob is to adjust the developing bias. Laser printer models such as HP, Canon, Epson, Lenovo has the knob. Print concentration also means to improve resolution, reduce excessive toner fixing will affect the resolution. The new production laser printers are generally with resolution enhancement (RET). The performance of  green laser pointer  has been further improved.
Slash or arcs can be filled with by RET way, the lattice hole defects, RET can not afford to do with the horizontal, vertical lattice. There are three ways: (1) mild (Lighi); ② The moderate (Medium); ③ The depth (Dark). RET can be combined with the print concentration choose to print fine text or images, also known as smoothing techniques. Different settings, and print out the pieces of different signs on the proofs. The developer magnetic roller: developing magnetic roller is an important component of the carrying of toner. Permanent core is not rotating, its role is the surface of the magnetic adsorption toner to the magnetic roller. The magnetic roller surface spray a layer of coarse graphite layer, so that the toner scraper to the formation of electron holes and conducive to the toner passing.
