Abstract: According to one embodiment, an image forming apparatus includes a log memory, an analysis unit, a determination unit, an extraction unit, and an output unit. The log memory stores error logs. The analysis unit analyzes an error content based on the logs stored in the log memory. The determination unit determines whether or not a notification of the error analyzed by the analysis unit is sent. The extraction unit extracts a log regarding the error for which the notification is sent, from the log memory, if the determination unit determines that the notification of the error is sent. The output unit outputs an error notification to which the log extracted by the extraction unit is attached.

Abstract: When image data from an external device is image data for proof printing, the number of pages of image data is calculated. Further, the percentage of a character image region and the percentage of a photographic image region in all the image data are determined. A reduction in toner consumption is determined according to the number of pages, the percentage of the character image region and the percentage of the photographic image region, and a document is then printed.
