<p>An image-forming apparatus includes a reception unit (202) configured to receive a start instruction and an end instruction entered by a service engineer who performs a maintenance work for the image-forming apparatus. A first holding unit (204) is configured to store first counter information obtained by the image-forming apparatus when the reception unit receives the start instruction. A second holding unit (204) is configured to store second counter information obtained by the image-forming apparatus when an operating state of the image-forming apparatus satisfies a first end condition. A generation unit (205) is configured to generate maintenance information based on the second counter information stored in the second holding unit if the operating state of the image-forming apparatus satisfies the first end condition and further satisfies a second end condition before the reception unit receives the end instruction from the service engineer.
