[A] OPC Drum [C] ITB
[B] Paper Transfer Roller [D] Image Transfer Roller (First Transfer Roller)
Images of each color are created and transferred to the ITB (image transfer belt) [C].
The paper transfer roller [B] transfers the toner image from the ITB to the paper.
This model uses the indirect transfer method to enhance the quality of transfer.
The indirect transfer method uses the resistance of the ITB to apply the bias to the drum. So, in this model, the
position of the image transfer roller is changed and so is its material.
As the image transfer method is changed, the paper transfer method is changed from the repulsion method to the
attraction method (the reason is explained below).
• Direct Image Transfer + Repulsion Transfer Method (C305):
The image transfer roller [A] transfers the image transfer bias to the drum [B]. The paper transfer bias
flows into the paper transfer roller [C].
• Indirect Image Transfer + Repulsion Transfer Method:
The image transfer roller [A] transfers the image transfer bias to the drum [B]. However, some of the
bias goes to the image transfer belt [C]. This causes harmful interference between the image transfer
current and paper transfer current.
