An image forming apparatus comprising: an image bearing member (1a, 1b, 1c, 1d); an intermediate transfer member to which an image formed on the image bearing member is transferred; a secondary transfer member forming a transfer nip, with the intermediate transfer member, in which the image is subsequently transferred from the intermediate transfer member to a recording medium, the recording medium to which the image has been transferred having a leading margin, at a leading end portion thereof, on which the image is not formed; a conveying means configured to convey the recording medium to the transfer nip; a motor configured to transmit a driving force for driving the conveying means toward the conveying means; and a control means configured to control the motor so as to change a conveyance speed at which the conveying means conveys the recording medium, wherein the control means is configured to control the motor so that the conveyance speed is a first speed, which is a constant speed and which is higher than a speed at which the intermediate transfer member is moved, before a leading edge of the recording medium reaches the transfer nip, characterized in that the control means is configured to control the motor so that the conveyance speed (Vr) is maintained at the first speed until the leading edge of the recording medium has reached the transfer nip, and so that the conveyance speed is reduced from the first speed to a second speed after the leading edge of the recording medium reaches the transfer nip and before the image is transferred from the intermediate transfer member to the recording medium at the transfer nip, and a time interval, between a timing when the leading edge of the recording medium reaches the transfer nip and a timing when the conveyance speed is reduced from the first speed to the second speed, is predetermined. an image bearing member (1a, 1b, 1c, 1d); an intermediate transfer member to which an image formed on the image bearing member is transferred; a secondary transfer member forming a transfer nip, with the intermediate transfer member, in which the image is subsequently transferred from the intermediate transfer member to a recording medium, the recording medium to which the image has been transferred having a leading margin, at a leading end portion thereof, on which the image is not formed; a conveying means configured to convey the recording medium to the transfer nip; a motor configured to transmit a driving force for driving the conveying means toward the conveying means; and a control means configured to control the motor so as to change a conveyance speed at which the conveying means conveys the recording medium, wherein the control means is configured to control the motor so that the conveyance speed is a first speed, which is a constant speed and which is higher than a speed at which the intermediate transfer member is moved, before a leading edge of the recording medium reaches the transfer nip, characterized in that the control means is configured to control the motor so that the conveyance speed (Vr) is maintained at the first speed until the leading edge of the recording medium has reached the transfer nip, and so that the conveyance speed is reduced from the first speed to a second speed after the leading edge of the recording medium reaches the transfer nip and before the image is transferred from the intermediate transfer member to the recording medium at the transfer nip, and a time interval, between a timing when the leading edge of the recording medium reaches the transfer nip and a timing when the conveyance speed is reduced from the first speed to the second speed, is predetermined.
