1. An image forming apparatus comprising:
a conveyance unit configured to convey a recording medium in a sub scanning direction; a recording head configured to reciprocatingly scan in a main scanning direction perpendicular to the sub scanning direction, to form an image on the recording medium conveyed by the conveyance unit; a reversing unit configured to reverse front and back sides of the recording medium and convey the reversed recording medium to the conveyance unit; and a control unit configured to control a conveyance speed at which the conveyance unit conveys the recording medium, wherein in a case of performing a double-sided printing, during the conveyance unit reciprocatingly conveying the recording medium, the recording head is controlled to form a first image on a first side of the recording medium, and during the conveyance unit conveying and ejecting the reversed recording medium, front and back sides of which are reversed by the reversing unit, the recording head is controlled to form a second image on a second side of the recording medium, and wherein the control unit is configured to control a first conveyance speed V1 upon forming the first image on the first side of the recording medium and a second conveyance speed V2 upon forming the second image on the second side of the recording medium to satisfy a relation
