1. An image forming apparatus, comprising:
a conveyance unit configured to convey a sheet on a conveyance path on which the sheet is conveyed;
a first conveyance path opening member configured to open a first portion of the conveyance path by the first conveyance path opening member being opened to allow a sheet to be removed from the first portion;
a second conveyance path opening member configured to open a second portion downstream of the first portion of the conveyance path in a sheet conveyance direction by the second conveyance path opening member being opened to allow a sheet to be removed from the second portion;
a sheet leading edge position detecting unit configured to detect a position of a leading edge of a stopped sheet on the conveyance path; and
a determination unit configured to determine, based on a detection result of the sheet leading edge position detecting unit, one of not conveying the stopped sheet, causing the conveyance unit to convey the stopped sheet toward the first portion, and causing the conveyance unit to convey the stopped sheet toward the second portion,
wherein, in a case where the determination unit determines to cause the conveyance unit to convey the stopped sheet toward the first portion, the conveyance unit starts to convey the stopped sheet in association with an operation of opening the first conveyance path opening member, and
wherein, in a case where the determination unit determines to cause the conveyance unit to convey the stopped sheet toward the second portion, the conveyance unit starts to convey the stopped sheet in association with an operation of opening the second conveyance path opening member.
