An fixing device comprises a heating member, a first heater, a second heater, and the heating member, a first temperature detector, a second temperature detector, and a controller configured to control energization to the first heater and the second heater based on an energization pattern for each control period. In a case where a length of the control period is T, a length of a period during which a first continuous energization control is T1, and a length of a period during which a second continuous energization control is T2, when a first condition represented by T1+T2<T is satisfied, the controller starts the second continuous energization control just after an end of the first continuous energization control.

An image processing apparatus which is capable of improving ease of operation for users and also improving security when destinations are made public. The image processing apparatus is shared by a plurality of users and capable of selecting a destination from a plurality of address books and carrying out file transmission to the destination. It is determined whether or not a user has logged in, and when it is determined that the user has logged in, only personal addresses for the logged-in user are displayed on a display unit. The personal destinations displayed on the display unit are switched to destinations other than the personal destinations according to selection by the user. When it is determined that the user has not logged in, all destinations which are registered in the plurality of address books are displayed on the display unit.

Image forming apparatus

An image forming apparatus includes an image forming unit configured to form an image on a sheet, a stacking portion on which the sheet having the image formed thereon is to be stacked, a first roller capable of forward and reverse rotations, a second roller capable of rotating with the first roller when the first roller makes a forward rotation, a third roller capable of rotating with the first roller when the first roller makes a reverse rotation and then the forward rotation, a regulation portion movable between a regulation position where entering of the sheet into a nip portion between the first and second rollers is prevented, and an allowing position where discharge of the sheet is allowed, and a movement unit configured to cause the regulation portion to be placed in the allowing position during forward rotation, and to be placed in the regulation position during reverse rotation.

Power control device, electrical apparatus, and image forming device

A power control device includes non-volatile memory, a controller, and a logic circuit. The non-volatile memory includes a function of externally outputting a logical state of a bit stored in a specific area as a state hold signal that indicates an ON/OFF state of a device function unit before a power cutoff. The controller controls the ON/OFF state of the device function unit and also writes the ON/OFF state of the device function unit to the specific area of the non-volatile memory. The logic circuit controls power supply to the controller on the basis of a logic level of the state hold signal from the non-volatile memory.

Fixing device and image forming apparatus

A fixing device includes a device body, a fixing unit, a pair of decurling units, and an open/close unit. The fixing unit is disposed on the device body to perform a fixing operation on a recording medium, and includes a removal assistance unit to assist removal of the recording medium. The pair of decurling units are disposed on the device body to correct a curl of the recording medium by holding the recording medium therebetween. The open/close unit is openably and closeably disposed on the device body to separate, when opened, the removal assistance unit from the fixing unit and one of the decurling units from the other decurling unit.

Print glossing

Print glossing is described. Print glossing can be performed on a glossing drum having a location affixed to a circumferential outer surface thereof, where the location transits from a first position in an apparatus having a first temperature range selected to enable reflow of ink applied to a substrate that is placed at the location to a second position in the apparatus having a second temperature range selected for clean release from the location of the ink applied to the substrate.

Information storage system including a plurality of terminals

A toner container includes a container body, an opening, a cover, a toner discharge port, a shutter, a cylindrical structure, protrusions, and an identifier. The shutter is attached to the cover and includes a main shutter covering the toner discharge port. The main shutter moves between a closed position to close the toner discharge port and an open position to open the toner discharge port. The protrusions are on both sides of the cover and protrude in a direction orthogonal to a toner container mounting direction. The identifier is on the cover to indicate a toner color. The cylindrical structure's leading end is downstream of leading ends of the protrusions in the mounting direction. The main shutter's leading end is downstream of the protrusions' leading ends in the mounting direction when the main shutter is in the closed position. The protrusions are downstream of the identifier in the mounting direction.

Electronic device

An electronic device includes: an operation section, a reception section, a human body detection sensor, and a mode switching section. The mode switching section switches the electronic device between a normal operation mode permitting a normal operation and a sleep mode in a power saving state based on presence or absence of a detection signal from the human body detection sensor. Then the mode switching section stops in a case where a state in which the reception section receives an operation made by use of the operation section continues for a predefined period of time the switching between the normal operation mode and the sleep mode based on the presence or absence of the detection signal.

Automatic document feeder and image forming apparatus including the same
