Abstract:
An image forming apparatus comprising:a latent image carrier on which a latent image is formed; a developer carrier for conveying a one-component non-magnetic developer and for developing the latent image in close proximity to said latent image carrier; voltage application means for applying an AC-superimposed bias voltage to said developer carrier; and a regulating member abutting against said developer carrier to regulate a thickness of a developer layer on said developer carrier, wherein the developer layer is formed with a line-shaped uneven conveying surface by said AC-superimposed bias voltage applied thereto, and wherein said regulating member has a semiconductive member provided at a distal end thereof to produce an electric potential difference between said semiconductive member and said developer carrier, to which said AC-superimposed bias voltage is applied, when regulating the thickness of the developer layer on said developer carrier.
