摘要： In a transfer device, a first side of a flexible guide plate faces to a recording medium being conveyed along a medium conveyance path to guide the recording medium toward an image carrying member. A support frame supports an upstream end portion of the guide plate, and includes an opposite portion disposed from and opposite to a second side (reverse to the first side) of the guide plate and a rib configured to protrude from the opposite portion toward the medium conveyance path. The rib has a first edge which is positioned at an upstream side and beyond which the guide plate protrudes downstream. The rib has an inclined surface extending from the first edge in a direction obliquely downstream toward the image carrying member. The guide plate includes an indentation to allow the guide plate to be deflected without being blocked by the rib.

摘要： In a transfer device, a flexible guide plate is disposed in a position upstream relative to a transfer position along a medium conveyance path, such that a first side of the guide plate faces to a recording medium being conveyed along the medium conveyance path. The guide plate has a downstream end portion that is angled by bending the guide plate. A support frame supports an upstream end portion of the guide plate and extends in a downstream direction beyond the downstream end portion to form an extension portion which is disposed opposite to a second side of the guide plate and toward which the downstream end portion extends obliquely downstream. The extension portion has a recess/hole formed in a position separated in an upstream direction from a first edge of the extension portion, to allow the downstream end portion to be moved without being blocked by the extension portion.

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.
