Abstract
An image forming apparatus includes: a detection unit configured to detect whether a cassette accommodating a sheet is in an attached state or in a non-attached state; a transfer roller configured to transfer an image to the sheet in a transfer region; a conveyance roller configured to convey, to the transfer region, a first sheet; a drive unit configured not to transmit the driving force to the conveyance roller in the non-attached state; and a determination unit configured to determine that an image defect has occurred when the detection unit detects that a state of the cassette has transitioned to the non-attached state, in a monitoring period including a period from a first timing at which the first sheet starts to be conveyed by the transfer roller, to a second timing.
