ABSTRACT:
A development apparatus for use with dry type copying apparatus having: a development roller, which is rotated in close proximity to a latent electrostatic image bearing recording material; a hopper for supplying an insulating toner onto the development roller; and a single developer regulating member in the form of a blade having an acute angle tip disposed at the edge of or right behind the outlet of the hopper in such manner that the top surface of the member forms an acute angle with the downstream side in the direction of development roller rotation of a tangent to the development roller at a point right under the tip of the development regulating member. Alternatively a single or a plurality of triboelectric charging members may be disposed at the edge of or right behind the outlet of the hopper of the respective angles with the top surfaces of the blades with respect to the respective tangents to the points on the surface of the development roller right under the respective tips varying from an acute angle to an obtuse angle in the direction of development roller rotation.
