摘要： An image forming apparatus includes at least one image carrier and a recording medium conveyor forming a transfer nip therebetween, a conveyance member disposed closest to the transfer nip on an upstream side of the transfer nip to convey the recording medium to the transfer nip, and a conveyance control mechanism to deactivate the conveyance member to stop providing a conveyance force to the recording medium after the leading edge of the recording medium has entered the transfer nip and before the trailing edge of the recording medium passes a point of force application and remaining in the inactive state until the recording medium passes the point of force application. The conveyance force remains unapplied to the recording medium from when the conveyance control mechanism deactivates the conveyance member to when the trailing edge of the recording medium passes the transfer nip.
