An image forming device that executes an image forming program for real-time mechanical control and another program, using a single cache memory for the image forming program and said another program. The image forming device includes: a cache lockdown unit that executes a cache lockdown to lock down a storage area of the cache memory that stores at least a portion of the image forming program necessary for image formation processing; and a print unit that executes the image formation processing while the storage area is locked down.

An electronic apparatus includes: a first storage unit divided into a plurality of first partitions that are used for respectively executing a plurality of different functions; a second storage unit different from the first storage unit; and a processor that acquires a size change request for changing a size of at least one of the first partitions, carries out processing for changing the size of at least one of the first partitions upon acquiring the size change request, and uses the second storage unit in executing at least one of the functions during the size change processing.

Provided is an image forming apparatus capable of presenting to a user movies that show operation steps for solving a maintenance event occurring in the apparatus without increasing the number of times the user needs to perform the operation of playing the movie. A CPU is configured to play a combination of a plurality of movies as a series of movies that show operation steps for solving a maintenance event occurring in the image forming apparatus. The CPU is further configured to determine a stop point at which the series of movies that is playing stops playing, based on stop point information set for each of the combination of the plurality of movies. The CPU is further configured to stop the series of movies that is playing at the determined stop point.

To provide an electronic device that is capable of displaying a warning indication of urging a replacement of a memory at an optimal timing. A system control calculate a warning indication threshold value based on a ratio of a value to a TBW (guaranteed write capacity), the value being a multiplication of a sum of the data write quantity per day that are defined for a for-system partition and a for-each function partition of the SSD and specific days (for example, 3 months) before the sum of write quantities reach the TBW. The system control part, which controls data write on the aforementioned partitions, causes a panel part to display the warning indication of urging a replacement of the SSD when a remaining write capacity of the TBW reaches the warning indication threshold value.

An image forming device executes a plurality of applications, and includes a scan controlling unit configured to instruct an image reading unit to read image data, and store the image data in an image data storage unit according to a request from the application; a display data generating unit configured to generate a display data of the image data stored in the image data storage unit, and store the display data in a display image data storage unit according to the request from the application, the display image data storage unit being inaccessible from the application; a display controlling unit configured to display the display data in a display unit according to the request from the application; and a deleting unit configured to delete the display data from the display data storage unit in response to a termination notice of use of the display data from the application.
