Electrostatic image magnetic developing process

摘要

A process for development comprises arranging an electrostatic image bearing member having electrostatic images on the surface and a developer carrying member at a predetermined space, an insulating magnetic developer containing 10-50% by weight of magnetic toner particles 20-35 microns in size being carried on the developer carrying member in a thickness thinner than the predetermined space, and transferring the insulating magnetic developer to the electrostatic image bearing member in the presence of a magnetic field. According to this process for development, there can be produced developed images of high fidelity, high density and high resolution and free from fog.
