Title:
Image forming device
Document Type and Number:
Japanese Patent JP5939783
Kind Code:
B2
Abstract:
An image forming apparatus configured to, in a state where a voltage is applied to a charging unit (202), determine a surface potential of an image bearing member (201) using a first voltage applied when a current value obtained by, after applying a predetermined voltage to a transfer unit (204), detecting the current value while changing the applied voltage to a positive direction reaches a discharge current value, and a second voltage applied to the transfer unit when a current value obtained by, after applying the predetermined voltage to the transfer unit, detecting the current value while changing the applied voltage to a negative direction reaches the discharge current value.
