DEVELOPER SEAL ABSTRACT OF THE DISCLOSURE A developer housing seal for electrophotographic apparatus in which an image developer material comprising magnetic particles is applied to a photoreceptor surface inside a developer housing held adjacent the photoreceptor. A magnetic seal is provided for retaining the developer in the developer housing, utilizing the magnetic particles, which are magnetically attracted by the magnetic fields of the seal. The seal is U- shaped, having a channel with two parallel spaced thin magnetic pole edge seal areas and a much wider recess therebetween to contain captured magnetic material. A seal is formed which reduces the likelihood of photoreceptor damage. A thin non- magnetic overlying protective shield slides off for cleaning of the seal. - 1 -
