发明名称 Image forming apparatus
摘要 An image forming apparatus includes: a photosensitive drum; a transfer roller configured to form a nip portion; and a sheet guide that is configured to guide a recording sheet. The sheet guide comprises: a conductor configured to face the recording sheet, and insulating ribs that are arranged corresponding to a printing area of the recording sheet in a width direction and are configured to protrude from the conductor to guide the recording sheet. The conductor comprises: a central portion, and a pair of end portions and are configured to protrude towards the recording sheet from a virtual plane extending from the central portion in the width direction. Protrusion amounts of the end portions with respect to the central portion are smaller than a protrusion amount of each rib from the central portion of the conductor.

主权项 1. An image forming apparatus comprising: a photosensitive drum; a transfer roller configured to form a nip portion together with the photosensitive drum to transfer an image formed on the photosensitive drum onto a recording sheet; and a sheet guide that is configured to guide the recording sheet having passed through the nip portion along a guide path in a conveyance direction, wherein the sheet guide comprises: a conductor configured to face the recording sheet, and a plurality of insulating ribs that are arranged, corresponding to a printing area of the recording sheet, in a width direction of the recording sheet substantially perpendicular to the conveyance direction and that are protruding from the conductor to guide the recording sheet, wherein the conductor comprises: a central portion arranged at an area corresponding to the printing area in the width direction, the central portion including a face that extends in both the width direction and the conveyance direction, and a pair of end portions, each of which is arranged at a corresponding side of the central portion in the width direction and outside the printing area and each of which is protruding towards the guide path relative to the central portion, and wherein the face of the central portion of the conductor is parallel to a face of the pair of end portions of the conductor, and wherein protrusion amounts of the end portions with respect to the central portion are smaller than a protrusion amount of each rib from the central portion of the conductor.
