In an image-forming apparatus, a sheet detector detects the recording sheet conveyed from the sheet accommodating unit by the pickup roller. A fixing unit includes a heating member configured to heat the recording sheet. A power supply unit supplies the heating member with electric power. A control device is configured to: output a signal controlling the pickup roller to convey the recording sheet from the sheet accommodating unit; determine, based on a detection result of the sheet detector, whether the pickup roller succeeds in conveying the recording sheet from the sheet accommodating unit; control the power supply unit to supply the heating member with the electric power such that the electric power per unit time does not exceed an upper limit; and set the upper limit depending on a determination result of whether the pickup roller succeeds in conveying the recording sheet from the sheet accommodating unit. |
