Magnetic Roller

Magnetic Roller

Magnetic Roller

Is the core component of the developing system for copiers and laser printers. It attracts developer (toner + carrier) via magnetic field and transports it evenly to the surface of the OPC drum to realize the development of electrostatic latent images.


Structure & Working Principle: 

It consists of a high-strength stainless steel core shaft, permanent magnets and an outer conductive rubber layer. Supported by bearings at both ends of the shaft for rotation, it absorbs developer by magnetic force to form an evenly thick developer layer. Cooperating with the magnetic doctor blade, it controls the thickness of the developer layer to achieve uniform development.


Performance Impact: 

The magnetic field strength, surface flatness and conductive uniformity of the magnetic roller directly determine print density and image sharpness. Aging or abrasion will cause faint printing, uneven images, heavy background haze and blurry lines. It is widely compatible with developer units of black-and-white and color copiers and laser printers from all brands.
