An image recording apparatus is configured to perform a conveying process of a recording medium using a conveying roller and a discharging roller, a recoding process of recording an image on the printing sheet when the conveying process is not performed, and an adjusting process. In the adjusting process, among a plurality of conveying processes performed within a period from the start of the conveying process for an n-th printing sheet until the timing which is after the start of the conveying process for an (n+1)-th printing sheet, the conveying amount of the printing sheet subject to at least one conveying process is adjusted such that a timing when the trailing end of the n-th printing sheet passes through the discharging roller is within one of the acceleration period and the deceleration period of the conveying process for the printing sheet.
