The Effect of Magnetic Roller Field Uniformity on Print Quality in Electrophotography
  DOI :  10.2352/ISSN.2169-4451.1998.14.1.art00030_2  Published OnlineJanuary 1998

The magnetic roller is a critical component in magnetic development systems in electrophotography. It serves to meter and deliver a uniform layer of toner to the development zone and to control the amount of toner delivered onto the photoreceptor. To ensure good print quality, the magnetic field around the roller must be designed properly and controlled carefully. In this paper, the effect of magnetic field non-uniformity on print quality is studied. The efficacy of a commercial magnetic roller mapping instrument for measuring and quantifying magnetic flux density characteristics is also investigated.
