Abstract
A sheet conveying device has a conveyance guide for guiding a sheet conveyed from a photosensitive drum and a transfer roller of a transfer portion to a pressurizing roller and a fixing roller of a fixing device, and the conveyance guide has a second guide surface and a third guide surface, the bending point of the guide surfaces being situated above the intersection of the nip plane of the photosensitive drum and the transfer roller and the nip plane of the pressurizing roller and the fixing roller and in a region on the side opposite to the direction in which the sheet is separated from the conveyance guide with respect to the nip planes.
Claims10
A sheet conveying device, comprising:
- upper and lower roller pairs;
- and a conveyance guide provided between the roller pairs and adapted to guide a sheet conveyed from said lower roller pair toward said upper roller pair, said two roller pairs arranged so that a nip plane of said upper roller pair intersects a nip plane of lower roller pair,
- wherein space is divided into inner and outer regions by a bent nip plane formed of both said nip planes intersecting each other, said conveyance guide situated in said outer region,
- wherein said conveyance guide has first and second guide surfaces for guiding the sheet which consists of two surfaces arranged vertically so as to intersect each other,
- wherein the intersection of the first and second guide surfaces is situated above the intersection of the nip plane of said lower roller pair and the nip plane of said upper roller pair, and
- wherein the intersection of the first and second guide surfaces is situated in said outer region divided by said bent nip plane.
An image forming apparatus comprising:
- a sheet conveying device including upper and lower roller pairs, and a conveyance guide provided between the roller pairs and adapted to guide a sheet conveyed from said lower roller pair toward said upper roller pair, said two roller pairs arranged so that a nip plane of said upper roller pair intersects a nip plane of lower roller pair;
- and
- an image forming portion for forming an image on the sheet conveyed by said sheet conveying device,
- wherein space is divided into inner and outer regions by a bent nip plane formed of both said nip planes intersecting each other, said conveyance guide situated in said outer region,
- wherein said conveyance guide has first and second guide surfaces for guiding the sheet which consists of two surfaces arranged vertically so as to intersect each other,
- wherein the intersection of the first and second guide surfaces is situated above the intersection of the nip plane of said lower roller pair and the nip plane of said upper roller pair, and wherein the intersection of the first and second guide surfaces is situated in said outer region divided by said bent nip plane.
