The abutted portion includes two abutted surfaces located obliquely with respect to an extending direction of the second surface. A difference between an angle formed by each of the two abutting surfaces and the extending direction of the first surface and an angle formed by each of the two abutted surfaces and the extending direction of the second surface is set larger than a maximum angular difference between the extending direction of the first surface and a movement direction in which the second tray moves with respect to the first tray.

IMAGE FORMING APPARATUS

An image forming apparatus includes: a housing; an image forming unit; a conveyor; a curved guide disposed downstream of the conveyor and configured to move between a near position where the curved guide in the housing guides the sheet and a far position farther from the conveyor than the near position; and a guide member extending from the conveyor toward the curved guide and configured to guide the sheet to the curved guide when the curved guide is located at the near position. The guide member has one end portion coupled to the conveyor and the other end portion movable with respect to the curved guide. When the curved guide is moved from the near position to the far position, the other end portion is moved in a direction from a downstream end toward an upstream end of the curved guide.

Image forming apparatus

An image forming apparatus includes a tray, a roller unit, an image forming unit, and a pressing mechanism. The roller unit includes a feed roller disposed above a downstream end portion of the tray in a sheet conveying direction in which a sheet is conveyed, a separation roller disposed downstream of the feed roller in the sheet conveying direction, and a roller holder pivotable about a rotation axis of the separation roller, the roller holder holding the feed roller rotatably about an axis of the feed roller and pivotably vertically. The pressing mechanism includes an arm member configured to press the roller holder such that the roller holder pivots downward, and a weight portion provided to the arm member and applying, to the arm member, a load in a direction in which the feed roller is raised from the upper surface of the sheet supported on the tray.

SHEET CONVEYING DEVICE, IMAGE READING DEVICE INCORPORATING THE SHEET CONVEYING DEVICE, IMAGE FORMING APPARATUS INCORPORATING THE SHEET CONVEYING DEVICE, AND IMAGE FORMING SYSTEM INCORPORATING THE SHEET CONVEYING DEVICE

A sheet conveying device includes conveyance passage forming bodies to define a sheet conveyance passage, a nip forming body to form a conveying nip region in the sheet conveyance passage, and a flexible plate body having a support portion to be attached to another body and having a downstream-side end portion as a free end in a sheet conveying direction. The support portion of the flexible plate body is located on an upstream side in the sheet conveying direction with respect to the conveying nip region. The free end being located on a downstream side in the sheet conveying direction with respect to the conveying nip region.

IMAGE FORMING APPARATUS AND FEEDING APPARATUS
20190233234 · 2019-08-01 ·

A feeding apparatus includes a feeding member, first and second conveying members, a separation member, and drive and control units. The feeding member feeds a recording material placed on a tray. The separation member and the first conveying member form a nip portion and separates recording materials at the nip portion. The second conveying member conveys a conveyed recording material. The drive unit drives at least the feeding member. The control unit controls to feed first and second recording materials such that a second recording material front edge passes the nip portion before a first recording material rear edge passes the nip portion, and controls to stop the second recording material after the second recording material front edge has passed the nip portion such that the first recording material rear edge reaches the second conveying member before the second recording material front edge reaches the second conveying member.

Image forming apparatus
