The invention provides an image forming apparatus and an image forming system. An information processing apparatus having a printer driver is connected with the image forming apparatus controlled by the printer driver by the network. The image forming apparatus comprises: an image reading portion which optically reads predetermined printed matter to input image data; a printing set value judging portion which judges printing set values when the printed matter is printed from the input image data; and an initial set value input portion which inputs the judged printing set values as initial setvalues of the printer driver. The initial set value input portion set printing set values obtained by reading printed matter on an initial set value input screen of a printer driver as the initial set values of the printer driver, and initial set values set to the initial set value input screen are changeable by a user.
