摘要： A fixing device fixing a toner image on a recording material, includes: a first blowing section that blows air against a leading edge of the recording material that has passed through a nip portion formed by a heated fixing member and a pressing member kept in pressure contact with the fixing member, and a second blowing section that blows air against the recording material that has passed through the nip portion, wherein an air speed of air blown out from a first blowing outlet is higher than that of air blown out from a second blowing outlet, wherein an air flow amount from the first blowing outlet is less than that from the second blowing outlet, and wherein the first and second blowing outlets are arranged at the same position in a direction in parallel with a rotational axis of the fixing member.

摘要： A sliding sheet for fixing devices in the present invention is inserted in between an endless belt constituting one member out of two members which form a nip section for fixing operation and a pressure member for pressing the endless belt from an inner surface side toward the other member out of the two members. The sliding sheet, which is made of a single resin, repeatedly has a thick section and a thin section at least with respect to a sliding direction of the endless belt due to substantial difference in resin amount per unit area corresponding to positions within a sheet surface.

摘要： This fixing device has a fixing portion coming into contact with one face of a sheet, a plurality of drive portions coming into contact with the other face of the sheet to nip the sheet with the fixing portion, and a control portion for driving a plurality of the drive portions. The drive portions are placed in a direction orthogonal to a transportation direction of the sheet. The control portion controls driving of the drive portions independently of each other so that a speed difference may be imparted to the transportation speed of the sheet in the direction orthogonal to the transportation direction of the sheet. Thereby, it becomes possible to stabilize passing posture of the sheet S, and therefore to decrease wrinkling and image failure attributed to the passing posture of the sheet.

摘要： An image forming apparatus has a plurality of image holding components set along a transportation path of a recording sheet, each image holding component being operable at a full-color mode and a monochrome mode and an image holding component used for forming a black image being located nearest to the driving source. The image forming apparatus further has a worm shaft which is parallel to the transportation path of the recording sheet with one end being connected to a driving source, a worm wheel being attached to each image holding component and engaging with a corresponding worm, a clutch set to the worm shaft between the image holding component for black and an image holding component next to the image holding component for black, with the engagement and disengagement of the clutch being performed in synchronization with a switching operation to switch between the monochrome mode and the full-color mode, a rotational position detection unit for detecting a rotational position of the worm wheel set on the image holding component for black, and a storage unit for storing a rotational position of the worm wheels set on the image holding components when the clutch is disengaged. The clutch control unit engages the clutch when the rotational position detected by the rotational position detection unit is equal to the rotational position stored in the storage unit.

摘要： In order to provide a driving mechanism for a photosensitive drum which is capable of reducing deformation of the shaft of the photosensitive drum caused by loads when transmitting a driving force, a drive transmission course 51 is diverged to at least two courses in a drive transmission system 42 for transmitting the drive force from a drive motor 41 to the photosensitive drum 25. Specifically, the last stage of the drive transmission course 51 is engaged with a passive member 47 provided to the drum shaft 25a at two or more points to connect and link the drive force, thereby diverging the directions of loads to several directions, by which irregular movements of the photosensitive drum or vibration caused by the deformation of the shaft is eliminated.

摘要： This invention concerns an image forming apparatus provided with a fixing device for fixing an image formed on a sheet. This apparatus comprises shutters for shielding opening parts formed in the fixing device for the passage of the sheet, a driver for switching the shutters between the opened state and the closed state, a sensor for detecting the presence or absence of the opened state of the shutters, and a CPU for setting the driver moving and controlling the opening or closing motion of the shutters. The CPU compares the signal to open or close the shutters and the signal from the sensor and prohibits the fixing device from producing a fixing motion when the sensor detects the closed state of the shutters in spite of the issuance of a signal to open the shutters. Owing to this construction, the otherwise possible blockage of the sheet by the shutters provided for the fixing device can be precluded because the fixing operation of the fixing device is prohibited when the shutters are closed in spite of the issuance of the signal to open the shutters.
