摘要:
The present invention provides a developing method for rendering a latent image supported on an image bearing member visible, and an apparatus therefor, in which a developer supporting member supporting thereon spherical granular developer prepared in substantially spherical form by a flow coater process or a spray drying process is maintained in opposed relation to an electrostatic image bearing member having a backing electrode so that the surface of the image bearing member and the developer on the developer supporting member are maintained in a mutually contact-free state, and an alternating voltage is applied to the developer supporting member to cause reciprocating motion of the developer in the developing area between the developer supporting member and the image bearing member.
摘要:
A developing method and apparatus in which a developer supporting member is opposed to a latent image bearing member with a clearance therebetween and developer is caused to be transferred from the developer supporting member to the latent image bearing member to effect development and wherein a first and a second developing portion are provided as the developer supporting member, these effect development in the named order to complete the developing step, a first alternating bias for causing the developer to be transferred so as to mainly develop the image end portion of the latent image is imparted to the first developing portion, and a second alternating bias for causing the developer to be transferred so as to mainly effect the development for reproducing the tone of the latent image is imparted to the second developing portion.
