    Abstract: An image forming apparatus monitors sleep-cancelling events, and when a sleep-cancelling event occurs, stores an identifier and a sleep-cancellation time of the event. If a start time of a sleep mode is reached when (i) the apparatus is in a standby mode and (ii) one or more sleep-cancelling events specifying sleep-cancellation times later than the start time have been stored, the apparatus calculates power consumption required to maintain the standby mode for a period from the start time to the earliest sleep-cancellation time, as a power-saving amount savable during the period. Also, a recovery power amount required for recovery from the sleep mode to the standby mode is calculated on the assumption that the sleep mode is started at the start time and is cancelled at the earliest sleep-cancellation time. Switching to the sleep mode is performed only when the power-saving amount is greater than the recovery power amount.

    Abstract: In a printer, three toner patches are primary-transferred successively to an intermediate transfer belt. Here, after the first toner patch passes through a belt cleaner and before the second toner patch reaches the belt cleaner, and after the second toner patch passes through the belt cleaner and before the third patch reaches the belt cleaner, the belt cleaner is operated to change the state of contact to the intermediate transfer belt to a different state. A density sensor detects density of the toner image on the intermediate transfer belt, and presence/absence of the toner patch is detected. When presence/absence of the first to third patches is detected alternately, it is determined that the belt cleaner is performing the operation described above.

    Abstract: A main body of an image forming apparatus includes a switching circuit provided for switching between a normal current which should be applied at a time of normal operation and a contact-corrosion preventing current which is set larger than the normal current. Each of the currents is to be applied to an imaging unit through the contacts between the main body and the imaging unit. A control section controls the switching circuit so as to temporarily switch from the normal current to the contact-corrosion preventing current at specified timing.
