Electrostatic image forming apparatus

摘要

In an image forming apparatus, the absolute value (¦VBH-VM¦) of the potential difference between a first development bias electric potential (VBH) and an intermediate electric potential (VM) is set to be smaller (¦VBH-VM¦<¦VBL-VM¦) than the absolute value (¦VBL-VM¦) of the potential difference between a second development bias electric potential (VBL) and the intermediate electric potential (VM).
