Abstract
A developing apparatus includes a developer carrying member for carrying developer, an elastic blade press-contacted to the developer carrying member to regulate a layer of developer formed on the developer carrying member, where the elastic blade comprises an electrically conductive layer, and a high resistance layer located at the developer carrying member side of the conductive layer, and an electric field generating device for forming an oscillating electric field between the developer carrying member and the conductive layer, wherein a maximum intensity of the electric field is not less than 10.sup.6 V/m.
