More Information
Summary:A development device configured to develop an electrostatic image formed on an image bearing member by applying a developing bias in a development operation includes a developer bearing member configured to bear a developer, a bias applying unit configured to apply an input waveform bias including an alternating component to the developer bearing member, a bias detection unit configured to detect information concerning an output waveform bias generated on the developer bearing member when the bias applying unit applies the input waveform bias to the developer bearing member, and a controller configured to execute a mode for controlling the developing bias to be applied to the developer bearing member based on the input waveform bias and the output waveform bias.
