• means for determining a color of sheets stored in said storing means attached to said main body;
• copy mode selecting means for selecting either a first copying mode in which a copy of all of the originals transported by said original transporting means is made using sheets of a first color, or a second copying mode in which a copy of a particular original among said plurality of original is made using a sheet of a second color and a copy of the remaining originals is made using sheets of said first color,
• detecting means for detecting whether said sheet storing means is attached to a predetermined position of the main body;
• and
• means for executing control so that a sheet is fed from said sheet storing means when it is detected that a sheet of a different kind in color is provided, a sheet is fed from a manual paper feed means when it is not detected that a sheet of different kind in color is provided, when said copying mode is selected.

An image forming apparatus comprising:

• original transporting means for transporting a plurality of originals set on a tray one by one to a platen;
• sheet feeding means having a plurality of feeding portions for feeding different types of sheets;
• a manual inserting portion of manually inserting sheets and feeding the manually inserted sheets;
• original distinguishing means for distinguishing a particular one of said originals based on an ordinal position of the one relative to all the other originals;
• sheet determining means for determining the type of sheets stored in said feeding portions and in distinguishing which feeding portions is stored a particular type of sheets for said particular original;
• control means for switching said feeding portions so that the particular original is copied on said particular type of sheet fed from the distinguished feeding portion and the other originals are copied on sheets other than the particular type of sheets;
• and
• means for feeding the sheets manually inserted to said manual inserting portion for the copy of the particular original when said sheet determining means determines an absence of the particular type of sheets stored in the feeding portions.

• sheet feeding means having a plurality to feeding portions of feeding different types of sheets;
• manual inserting portion for manually inserting sheets and feeding the manually inserted sheets;
• original distinguishing means for distinguishing a particular one of said originals based on an ordinal position of the one original relative to all the other originals;
• and
• control means for controlling sheet feeding so that the particular original is copied on the sheet fed from said manual inserting portion and the the originals are copied on the sheets fed from one of said feeding portions.

An image forming apparatus comprising:

• a main body;
• original transporting means for transporting a plurality of originals set on a tray one by one to a platen;
• a plurality of developing units containing developer at least one of which is removable attached to the main body of the apparatus;
• detecting means for detecting a detachment of said developing unit from the main body;
• original distinguishing means for distinguishing a particular one of said originals based on an ordinal position of the one relative to all the other originals
• control means for energizing one of said developing units for copying the particular original and energizing another developing unit for the other originals to copy the particular original in a different color from a color of the other originals;
• and
• means for preventing a copying operation when said detecting means detects the detachment.

• means for providing images of plural pages;
• determining means for determining a particular page of said plural pages from the other pages;
• sheet feeding means having a plurality of feeding portions for feeding different types of sheets;
• a manual inserting portion for manually inserting sheet sand feeding the manually inserted sheets;
• distinguishing means for distinguishing in which feeding portion is stored particular sheets for said particular page;
• control means for switching said feeding portions so that the image of the particular page is formed on said particular sheet fed from the distinguished feeding portion and the images of the other pages are formed on sheets other than the particular sheet;
• and
• means for feeding sheets manually inserted to said manual inserting portion for forming the image of the particular page when said distinguishing means determines an absence of particular sheets in the sheet feeding means.
