An image forming apparatus transporting sheets of paper at a predetermined interval and forming an image on the sheets has, as modes for controlling the predetermined interval, a first mode of suspending a next paper feeding operation, for a predetermined time and for every predetermined number of sheets of paper and a second mode of expanding the interval of transportation between the paper feeding operations while continuing the transportation. The image forming apparatus decides whether a predefined first condition for starting control of the interval is satisfied during normal printing, determines a mode of the control in response to a decision that the condition is satisfied, and performs the control in the determined mode. The image forming apparatus calculates power consumption in each mode from the decision that the condition is satisfied to completion of uncompleted printing, and selects a mode in which the power consumption is relatively lower.

Image forming apparatus

Provides is an image forming system, comprising an image forming device and an information processing device connected to the image forming device, further comprising a function-detecting unit detecting that a second function is added to the image forming device having a first function, and a notification unit notifying the user using the first function of the fact that the second function is added when addition thereof is detected by the function-detecting unit.
