Abstract: An image forming system, having a recording head, a sheet conveyer, an inverting mechanism, and a controller, is provided. The sheet conveyer conveys a sheet in a sheet-conveying direction. The sheet is nipped at nipping points located at positions upstream and downstream in the sheet-conveying direction with respect to a discharging position. The inverting mechanism inverts the sheet from a first side to the second side. The controller determines an initial arrangement of the sheet in the sheet conveyer where image-forming on the second side starts, and controls a length of a period between time, when image-forming on the first side of the sheet in the posture with the first side facing the recording sheet is completed, and time, when the image-forming on the second side of the sheet inverted and refed to the sheet conveyer starts, based on the determined initial arrangement of the sheet in the sheet conveyer.

Abstract: There is provided image recording apparatus including: memory and controller. The controller is configured to store, in the memory, first identification information for identifying recorded image and minimum margin value being a minimum value of partial image margins of recorded partial images. The controller is configured to obtain second identification information for identifying image-to-be-recorded. In a case that second identification information is same as first identification information stored, the controller is configured to determine whether the minimum margin value is smaller than threshold or not, and then: in a case that the minimum margin value is smaller than threshold, the controller is configured to derive an edge position of the sheet, and then execute ejection based on the derived edge position; and in a case that the minimum margin value in not smaller than threshold, the controller is configured to execute the ejection without deriving the edge position.
