Magnetic Roller Blade

Magnetic Blade

Also known as Doctor Blade, is installed in the developer unit of copiers and laser printers and serves as one of the core components of the developing system. Working in coordination with the magnetic roller, it controls the thickness and uniformity of developer to guarantee a stable and reliable developing process.


It adopts a high-performance special stainless steel bracket. By precisely controlling the gap between itself and the magnetic roller surface, it evenly coats the developer (toner + carrier) onto the magnetic roller to form a developer layer with consistent thickness and realize uniform development.


The gap precision and blade edge flatness of the magnetic blade directly affect the uniformity of print density. Wear or deformation of the blade will cause faint printing, uneven images, heavy background haze and other defects.
