Claims (6)
前記転写材の抵抗値が高くなると、前記抵抗値変更手段は前記接触転写部材の温度を低くして、前記接触転写部材の抵抗値を高くするモードを実行することを特徴とする画像形成装置。 An image carrier that carries a toner image, and a contact transfer member that contacts the image carrier and applies a voltage to transfer the toner image on the image carrier to a transfer material, and the resistance value decreases as the temperature increases. If, as the resistance value before Symbol contact transfer member is changed, and a resistance value changing means for heating or cooling the contact transfer member,
When the resistance value of the transfer material increases, the resistance value changing unit executes a mode in which the temperature of the contact transfer member is lowered and the resistance value of the contact transfer member is increased .
前記転写材が厚くなると、前記抵抗値変更手段は前記接触転写部材の温度を低くして、前記接触転写部材の抵抗値を高くするモードを実行することを特徴とする画像形成装置。 An image carrier that carries a toner image, and a contact transfer member that contacts the image carrier and applies a voltage to transfer the toner image on the image carrier to a transfer material, and the resistance value decreases as the temperature increases. If, as the resistance value before Symbol contact transfer member is changed, and a resistance value changing means for heating or cooling the contact transfer member,
When the transfer material becomes thick, the resistance value changing unit executes a mode in which the temperature of the contact transfer member is lowered and the resistance value of the contact transfer member is increased .
前記トナー像が転写される際に前記転写材が移動する方向に直交する方向における、前記転写材の長さが短いと、前記抵抗値変更手段は前記接触転写部材の温度を低くして、前記接触転写部材の抵抗値を高くするモードを実行することを特徴とする画像形成装置。 An image carrier that carries a toner image, and a contact transfer member that contacts the image carrier and applies a voltage to transfer the toner image on the image carrier to a transfer material, and the resistance value decreases as the temperature increases. If, as the resistance value before Symbol contact transfer member is changed, and a resistance value changing means for heating or cooling the contact transfer member,
When the length of the transfer material is short in a direction orthogonal to the direction in which the transfer material moves when the toner image is transferred, the resistance value changing unit lowers the temperature of the contact transfer member, and An image forming apparatus that executes a mode for increasing a resistance value of a contact transfer member .
