Abstract:
A development device includes a power source capable of applying a second voltage higher than a first voltage to be applied to a developer bearing member, a scattering prevention electrode that is arranged opposite the developer bearing member and to which the second voltage is applied from the power source, and a step-down circuit. The step-down circuit steps down a voltage from the power source from the second voltage to the first voltage to apply the stepped-down voltage to the developer bearing member.

Claim (Index 1):
A development device comprising:\n a developer container configured to store developer including toner and carrier; a rotatable developer bearing member configured to bear and convey the developer inside the developer container to develop an electrostatic latent image formed on an image bearing member; a magnetic field generation member arranged inside the developer bearing member, the magnetic field generation member including:\n a development pole positioned opposite the image bearing member, and \n a stripping pole arranged on a downstream side of the developer pole in a rotational direction of the developer bearing member and configured to strip the developer on the developer bearing member from the developer bearing member, \n an electrode portion arranged between the development pole and the stripping pole and opposite the developer bearing member; a direct current power source; and an electric circuit configured to apply voltage having a same polarity as a normal charge polarity of the toner to each of the developer bearing member and the electrode portion from the direct current power source, wherein the voltage to be applied to the electrode portion has an absolute value greater than an absolute value of the voltage to be applied to the developer bearing member.
