Abstract
This specification discloses a method of toner transfer development in which a low frequency alternating electrical bias is applied to the space between a latent image bearing member and a developer carrying member to develop the latent image on the latent image bearing member, and an apparatus for carrying out the same method. This bias has a first process in which reciprocal movement of developer particles is effected also between the non-image area of the latent image bearing member and the developer carrying member, and a second process in which the intensity of the bias is adjusted so that one-sided movement of developer particles from the developer carrying member to the image area and one-sided movement of developer particles from the non-image area to the developer carrying member may take place.
