ABSTRACT:
A developing apparatus includes a developer carrying member, disposed opposite to an image bearing member, for carrying developer which is caused to jump from the developer carrying member to the image bearing member to develop an electrostatic latent image formed on said image bearing member by creating an oscillation electric field between the image bearing member and the developer carrying member at an opposing portion where the image bearing member and the developer carrying member are opposed to each other; and a jumping developer regulation member for regulating an area in which the developer is caused to jump in the opposing portion. The jumping developer regulation member is disposed apart from the developer carried by the developer carrying member and is an insulating member or an electrically floating member.
