An image processing apparatus includes: a conveyer configured to convey a sheet; a first introducing part configured to introduce a first-type sheet toward the conveyer; a second introducing part configured to introduce a second-type sheet different from the first-type sheet toward the conveyer; a cover configured to be displaced between an open state, in which the second introducing part is opened, and a closed state, in which the first introducing part is opened and the second introducing part is closed; an image processor configured to perform image processing according to a sheet conveyed by the conveyer; and a controller, wherein in a case where the cover is in the closed state, the controller performs a first setting process to set a first image processing condition corresponding to image processing according to the first-type sheet.
