Abstract: A management device includes an input device that receives an input of first information indicating a type of an optional function of an image forming apparatus, second information for issuing a license key for the optional function, third information indicating an address of the image forming apparatus, and fourth information for logging in to the image forming apparatus, a requester that transmits an instruction to issue the license key, by transmitting the second information to a license key issuing source that issues the license key for the optional function of the type indicated by the first information, and a transmitter that logs in to the image forming apparatus at the address indicated by the third information, by transmitting the fourth information, and transmits the license key, received from the license key issuing source in response to the instruction of the requester, to the image forming apparatus.

Abstract: An image processing apparatus incorporated in an image forming apparatus includes a data acquisition unit, a proofreading processing unit, and an image generating unit. The data acquisition unit acquires data to be proofread representing sentences that are targets of proofreading. The proofreading processing unit proofreads the data to be proofread acquired by the data acquisition unit, and detects an erroneous writing including an error, and a regular notation representing a correct form of the erroneous writing. The image generating unit synthesizes an image representing the erroneous writing and the regular notation detected through the proofreading process performed by the proofreading processing unit with the data to be proofread, to thereby generate a proofreading result image.
