Claim Text:
1. An image forming apparatus comprising: a rasterization processing unit that performs rasterization processing on image data using a state parameter to generate raster image data; an image forming unit that forms an image on a recording medium on the basis of the generated raster image data; a first storage unit that saves, as a set of job data, the image data and the raster image data generated from the image data; an update unit that updates the state parameter; and a job management unit that, in response to a received processing request targeting at least one set of job data, executes processing of backup from the first storage unit into a second storage unit or restoration from the second storage unit, wherein (1) when determining that the raster image data included in the at least one set of job data as a target of the processing has been generated using any state parameter other than a current state parameter, the job management unit executes the processing for the at least one set of job data except for the raster image data, whereas (2) when determining that the raster image data included in the at least one set of job data as the target of the processing has been generated using the current state parameter, the job management unit executes the processing for the at least one set of job data including the raster image data.
