Abstract
An image forming apparatus comprising an image bearing member, a transfer mechanism that transfers a developer image formed on the image bearing member, a charger that charges the image bearing member, a first high voltage power supply substrate that applies a first voltage to the transfer mechanism, and a second high voltage power supply substrate that applies a second voltage to the charger, wherein the second voltage has a polarity opposite to the first voltage.
Claims20
An image forming apparatus comprising:
- an image bearing member;
- a transfer mechanism that transfers a developer image formed on said image bearing member;
- a charger that charges said image bearing member;
- a first high voltage power supply substrate that applies a first voltage to said transfer mechanism;
