Abstract
An image forming apparatus comprises: a revolving image bearing member on which a toner image is formed; a transfer member that is provided at a position facing the surface of the image bearing member and transferring the toner image electrostatically on a transfer sheet traveling between the image bearing member and the transfer member; a static charge eliminator generating an electric field for discharging the electric charge on the transfer sheet for separation of the transfer sheet carrying the transferred toner image from the image bearing member; and a conductive member that is provided between the static charge eliminator and the transfer member.
Claims21
An image forming apparatus, comprising:
- a revolvable image bearing member on which a toner image is formed;
- a transfer member provided against a surface of the image bearing member for transferring a toner image electrostatically on a transfer sheet traveling between the image bearing member and the transfer member;
- a static charge eliminator operable to generate an electric field to remove the electric charge on the transfer sheet for separation of the transfer sheet carrying the transferred toner image from the image bearing member;
- and
- a conductive member provided between the static charge eliminator and the transfer member, wherein
- the distance between a leading edge of the static charge eliminator and the transfer sheet is made longer than the distance between a leading edge of the conductive member and the transfer sheet.
An image forming apparatus comprising:
- a revolvable image bearing member on which a toner image is formed;
- a transfer member provided against a surface of the image bearing member for transferring a toner image electrostically on a transfer sheet traveling between the image bearing member and the transfer member;
- a static charge eliminator operable to generate an electric field to remove the electric charge on the transfer sheet for separation of the transfer sheet carrying the transfer toner image from the image bearing member;
- a conductive member provided between the static charge eliminator and the transfer member;
- and
- an insulating member provided between the static charge eliminator and the conductive member, wherein
- the distance between a leading edge of the static charge eliminator and the transfer sheet is made longer than the distance between a leading edge of the conductive member and the transfer sheet, and
- a leading edge of the insulating member is almost on a straight line connecting the leading edge of the static charge eliminator and the leading edge of the conductive member.
An image forming apparatus comprising:
- a revolvable image bearing member on which a toner image is formed, an electrostatic latent image being formed on the image bearing member and a toner image being formed by electrostatic adsorption of toner particles onto the electrostatic latent image, the image bearing member including a photosensitive drum revolving around an axis thereof;
- a transfer member provided against a surface of the image bearing member for transferring the toner image electrostatically on a transfer sheet traveling between the image bearing member and the transfer member, the transfer member being a transfer roller revolving around an axis thereof while a negative voltage is applied thereto;
- a static charge eliminator operable to generate an electric field to remove the electric charge on the transfer sheet for separation of the transfer sheet carrying the transferred toner image from the image bearing member;
- and
- a conductive member provided between the static charge eliminator and the transfer member.
