画像形成装置
Document Type and Number:
Japanese Patent JP4532629
Kind Code:
B2
Abstract:
The present invention provides an image forming apparatus which has an image bearing body for bearing a toner image, a transferring member for forming a nip with the image bearing body to pinch a transferring material and for transferring the toner image on the image bearing body to the transferring material, voltage applying device for applying a transfer voltage to the transferring member, voltage detecting device for detecting an applied voltage at which a predetermined current flows through the transferring member before a transferring operation, current detecting device for detecting a current flowing when a voltage based on a detected voltage of the voltage detecting device is applied to the transferring member in a condition where a tip end of the transferring material is present at the nip, and voltage determining device for determining the transfer voltage after the tip end of the transferring material, based on a detected current by the current detecting device.
