In an electrophotographic sheet-fed front/back printing machine which is capable of duplex printing and which can be installed in a reduced space, sheets of paper fed from a sheet supply are fed out by a sheet transport conveyer onto an impression cylinder of an electrophotographic printing section in which each of the sheets are printed on one side. The sheets printed on one side are turned over from front to back by a sheet turnover transport unit and are allowed to fall and be supplied onto the sheet transport conveyer. The sheets are each fed again onto the impression cylinder and printed on the remaining other side. Sheets printed on both sides are transported by a printed-sheet transport unit to a print output receptacle in which they are received.

A fixing apparatus includes a fixing drum having a heating heater internally equipped therein, the fixing drum positioned spaced part and downstream from a sheet delivery site at a downstream-most side of printing units and is adapted to rotate at a peripheral speed identical to a speed of travel of the sheet of paper. A first sprocket is positioned adjoining the sheet delivery site at the downstream-most side of the printing units, and a second sprocket is positioned coaxially with the fixing drum and being adapted to rotate integrally with the fixing drum. A conveyer chain having a gripper is wound around and engaging with the first and second sprockets to wind and convey a sheet of paper on a peripheral surface of the fixing drum upon gripping in turn with the gripper the sheet of paper traveling from the sheet delivery site at the downstream-most side.

Arbitrary source image data, and destination image data obtained by retouching the source image data are recorded. When the user sets, using an image sensing mode setting unit, an image sensing mode, image reproduction parameters of which are to be changed, and instructs to execute a parameter change process, a parameter determination unit changes the image reproduction parameters using the source and destination image data. The parameter determination unit generates a color conversion list by comparing the two image data, and changes the image reproduction parameters in the image sensing mode set by the image sensing mode setting unit using the color conversion list. In this way, an image can be reproduced using the image reproduction parameters that reflect the contents retouched by the user, and color setups of user's preference can be given to an image to be reproduced.
