Abstract
A fixing device may include a first fixing member, and a second fixing member, and may be configured to heat-fix a developer image on a recording sheet at a fixing nip formed between the first fixing member and the second fixing member. The fixing device may further include a charge-removing member arranged upstream of the fixing nip in a conveyance direction of the recording sheet and in a vicinity of a conveyance path of the recording sheet conveyed towards the fixing nip, and including a main body part and an end edge positioned at an edge of the main body part, and an insulating member arranged between the conveyance path and at least the entire end edge of the charge-removing member.
Claims21
An image forming apparatus comprising:
- a photosensitive member having a surface, on which a developer image is configured to be formed;
- a transferring member arranged to face the photosensitive member and configured to transfer the developer image formed on the surface of the photosensitive member to a recording sheet at a transfer nip formed between the photosensitive member and the transferring member;
- and
- a fixing device including a first fixing member and a second fixing member, and configured to heat-fix the developer image transferred on the recording sheet from the photosensitive member at a fixing nip formed between the first fixing member and the second fixing member;
- wherein the fixing device further includes:
- a charge-removing member arranged along a conveyance path of the recording sheet conveyed from the transfer nip to the fixing nip in a conveying direction, the charge-removing member including:
- a main body part;
- an upstream end edge positioned at an edge of the main body part at an upstream side of the conveying direction;
- a downstream end edge positioned at an edge of the main body part at a downstream side of the conveying direction;
- and
- side end edges positioned at edges of the main body part at both sides in a direction perpendicular to the conveying direction;
- and
- an insulating member arranged between the conveyance path, which is downstream of the transfer nip and upstream of the fixing nip, and at least an entirety of the upstream end edge and the downstream end edge of the charge-removing member.
A fixing device comprising:
- a first fixing member;
- a second fixing member, wherein the fixing device is configured to heat-fix a developer image on a recording sheet at a fixing nip formed between the first fixing member and the second fixing member;
- a charge-removing member arranged upstream of the fixing nip in a conveyance direction of the recording sheet and along a conveyance path of the recording sheet conveyed towards the fixing nip in a conveying direction, the charge-removing member including
- a main body part;
- an upstream end edge positioned at an edge of the main body part at an upstream side of the conveying direction;
- a downstream end edge positioned at an edge of the main body part at a downstream side of the conveying direction;
- and
- side end edges positioned at edges of the main body part at both sides in a direction perpendicular to the conveying direction;
- and
- an insulating member arranged between the conveyance path, which is downstream of a transfer nip at which a developer image is transferred to the recording sheet and upstream of the fixing nip, and at least an entirety of the upstream end edge and the downstream end edge of the charge-removing member.
