Image forming apparatus

摘要

An image forming apparatus includes an image forming portion forming an image on a sheet, a first sheet conveyance path guiding the sheet to the image forming portion, a second sheet conveyance path guiding the sheet on which an image has been formed by the image forming portion, and a re-conveyance path connecting the second sheet conveyance path and the first sheet conveyance path. The image forming apparatus further includes a connecting path connecting a point on the way of the second sheet conveyance path with a point on the way of the re-conveyance path and is configured to convey a sheet to the re-conveyance path through the connecting path.

1. An image forming apparatus comprising:
an image forming portion configured to form an image on a sheet; a first sheet conveyance path configured to guide the sheet to the image forming portion; a second sheet conveyance path configured to guide the sheet on which an image has been formed by the image forming portion; a re-conveyance path connecting the second sheet conveyance path and the first sheet conveyance path; a first rotary member configured for bidirectional rotation and arranged at an end portion of the second sheet conveyance path, the first rotary member being configured to reverse the sheet on the second sheet conveyance path and directly convey the sheet to the re-conveyance path from the second sheet conveyance path; a connecting path connecting a point on the way of the second sheet conveyance path with a point on the way of the re-conveyance path; a second rotary member configured for bidirectional rotation and arranged downstream, in a sheet conveying direction, of a branching point where the connecting path branches from the second sheet conveyance path on the second sheet conveyance path, the second rotary member being configured to reverse the sheet on the second sheet conveyance path and convey the sheet to the connecting path from the second sheet conveyance path; a guide unit arranged upstream, in the sheet conveying direction, of the second rotary member on the second sheet conveyance path, and being configured to switch between a first position guiding the sheet toward the second rotary member and a second position guiding the sheet reversed by the second rotary member toward the connecting path; and a control portion configured to control the guide unit such that the guide unit switches from the first position to the second position after a rear end of the sheet passes through the branching point and guides the sheet reversed by the second rotary member to the connecting path in a case of conveying the sheet to the re-conveyance path via the connecting path.
