Claim:
A copying apparatus comprising: a reader configured to read an image on a document; an image forming unit configured to form on a recording medium the image read by the reader; a controller configured to judge whether the image read by the reader is a color image or a black-and-white image and trigger the image forming unit to form a mark for image adjustment after the reader starts reading the image on the document and before the image forming unit starts forming the color image on the recording medium, if the controller judges that the image read by the reader is the color image; and an image adjustment sensor configured to sense the mark formed by the image forming unit; wherein the controller performs an image adjustment on the image read by the reader based on the mark sensed by the image adjustment sensor, wherein the image forming unit forms on the recording medium the image subjected to the image adjustment, wherein the controller judges whether a work amount since the last time the image forming unit forms the mark is not less than a predetermined value indicating that execution of the image adjustment is coming up soon, wherein if the controller judges that the work amount is not less than the predetermined value, the controller judges whether the image read by the reader is the color image or the black-and-white image, and wherein if the work amount is less than the predetermined value, the controller does not judge whether the image read by the reader is the color image or the black-and-white image.
