Abstract:
1. An image forming apparatus comprising a first control unit that controls the image forming apparatus, and a second control unit that controls image formation processing, said first control unit comprising: a start request output unit that outputs a start request to start image formation to said second control unit; and a data output unit that outputs image data for image formation to said second control unit in accordance with a synchronization signal output from said second control unit, and said second control unit comprising: a synchronization signal output unit that generates the synchronization signal and outputs the synchronization signal to said first control unit in response to the start request from said first control unit; an execution unit that executes image formation based on the image data output from said first control unit in accordance with the synchronization signal; a measuring unit that measures a period from output of the synchronization signal to reception of a next start request output from said first control unit; and a model specifying unit that specifies a model of the image forming apparatus in accordance with the period measured by said measuring unit.
