摘要： An image forming apparatus which reduces downtime by starting image density detection without waiting for identification of the same position on a rotary member. A detection unit detects a surface condition of a rotary member on which a toner image on a photosensitive drum is transferred. An identifying unit matches first data detected by the detection unit on a reference point on the surface of the rotary member and second data detected by the detection unit after obtainment of the first data to identify the reference point. A control unit controls image density based on a detection result obtained by the detection unit on a base of the rotary member corresponding to a range where a measurement image is formed and an obtained detection result on the measurement image by referring to the reference point identified as a reference.

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.
