    摘要： A first log indicating that a system is running is recorded in a second storage unit before a first difference log is recorded in the second storage unit after system startup, and a second log indicating that the system halts is recorded in the second storage unit following the difference log, at the time of normal system halt, and it is judged whether normal system halt has been performed or an incorrect power-off sequence has been performed last time, based on a recorded state of the first and second logs in the second storage unit, at the time of system startup, thereby detecting an incorrect power-off easily and reliably.

    摘要翻译： 在系统启动之前，将第一差异日志记录在第二存储单元中之前，将指示系统运行的第一日志记录在第二存储单元中，并且指示系统暂停的第二日志记录在第二存储单元之后 差异日志，在正常系统停止时，基于第二存储器中的第一和第二日志的记录状态，判断是否正在执行正常系统暂停或者上次执行错误的断电顺序 单元，在系统启动时，容易可靠地检测出不正确的断电。

    摘要： A memory system comprising a volatile memory unit, a nonvolatile memory unit, and a controller that performs data transfer between a host system and the nonvolatile memory unit via the volatile memory unit stores management information including a storage position of the data stored in the nonvolatile memory unit during a startup operation into the volatile memory unit, and performs, while updating stored management information, data management in the volatile and nonvolatile memory units based on the stored management information. The nonvolatile memory unit includes a snapshot storing area storing a snapshot which is the management information stored in the volatile memory unit at a certain point, a main log storing area storing a main log which is an update information of the management information stored in the volatile memory unit, and a backup log storing area storing a backup log having contents same as contents of the main log. The controller stores the management information of the volatile memory unit in the snapshot storing area as a snapshot when a predetermined condition is satisfied, and sequentially stores the main log in the main log storing area when the management information is changed and the backup log in the backup log storing area.

    摘要： An image forming apparatus of the present invention includes a fixing device in which a cleaning mechanism for collecting toner left on a heat roller is arranged. When a preselected number of prints are output after the end of a printing job, a cleaning operation for cleaning the heat roller is executed. When a power-supply OFF request arrives while the cleaning operation is under way, a power-supply OFF operation is postponed until the cleaning operation ends.

    摘要： When a new process cartridge is detected, that new process cartridge is initialized. A flag that indicates initialization status of the new process cartridge is set and stored. When a new process cartridge is detected, the flag is set to indicate non-initialization, the flag is maintained in that status during the initialization of the new process cartridge is being performed by the initialization unit, and the flag is set to indicate initialization completion when the initialization of the process cartridge is completed normally.
