摘要： An image transfer device provided in an image forming apparatus in which, employing an endless belt as an intermediate transfer member, image transfer is performed at nip positions of a primary transfer portion and secondary transfer portion. Generation of warp in the transferred image resulting from transmission of fluctuations in load and torque of the endless belt generated at the nip position of one transfer portion nip to the nip position of the other transfer portion is prevented. The endless belt is turned between rollers and the endless belt is individually driven at the primary transfer portion and secondary transfer portion by drive sources to generate deflection between the primary transfer portion and the secondary transfer portion.

摘要： An image forming apparatus of the present invention includes a printer engine for forming an image on a paper sheet fed from a paper cassette. A paper feeder feeds the paper sheet from the paper cassette to the printer engine while separating it from the other paper sheets stacked on the cassette. A switchback path branches off the transport path of the paper feeder for temporarily storing the paper sheet fed from the paper cassette. The paper sheet fed from the paper cassette enters the switchback path with its leading edge at the head. A roller pair is positioned on the switchback path for switching back the paper sheet received in the switchback path such that the paper sheet leaves the switchback path toward the printer engine with its trailing edge at the head.

摘要： A copier capable of binding copy papers at their center or their edge as desired. A bookbinding device is operatively connected to a paper outlet of the copier. To bind the papers at their center, a folding mechanism of the bookbinding device is activated first in order to form a crease along the center of each copy paper. Then, a binding mechanism of the bookbinding device is activated to sequentially stack the papers in an upwardly convex form and such that the creases face upward in alignment and, then, stich the papers together along the aligned creases by means of a stapler or the like. The bound papers are discharged to a stacking mechanism of the bookbinding device in a developed position so as to be stacked there while being folded double in the creases.

摘要： A nip formation pad includes a base, a high thermal conduction member, and an attachment. The high thermal conduction member has a thermal conductivity greater than a thermal conductivity of the base. The attachment is attached to the high thermal conduction member by elastic deformation of the attachment on the base held between the high thermal conduction member and the attachment.

摘要： A fixing device includes a fixing rotator, an opposed rotator disposed opposite the fixing rotator, a pressure pad, a lateral end heater, and a thermal conduction aid. The pressure pad presses against the opposed rotator via the fixing rotator to form a fixing nip between the fixing rotator and the opposed rotator. The lateral end heater is disposed on the pressure pad to heat a lateral end of the fixing rotator in the axial direction of the fixing rotator. The thermal conduction aid is interposed between the pressure pad and the fixing rotator to decrease a temperature gradient of the fixing rotator in an axial direction of the fixing rotator. The pressure pad includes a nip-side face disposed opposite the thermal conduction aid. The lateral end heater includes a nip-side face being disposed opposite the thermal conduction aid and projecting beyond the nip-side face of the pressure pad.

摘要： A fixing device includes fixing rotator, a heater to heat the fixing rotator, a pressure rotator disposed opposite an outer circumferential surface of the fixing rotator, a pressure pad disposed opposite an inner circumferential surface of the fixing rotator, a support to support the pressure pad, and a thermal conduction aid to conduct heat in an axial direction of the fixing rotator. The pressure pad presses against the pressure rotator via the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. The pressure pad includes a nip-side face disposed opposite the inner circumferential surface of the fixing rotator. The thermal conduction aid covers the nip-side face of the pressure pad. The nip-side face of the pressure pad includes at least one mouth therein defining a non-contact area in which the pressure pad does not contact the thermal conduction aid.

摘要： A fixing device includes a fixing rotator rotatable in a predetermined direction of rotation and a nip formation pad disposed inside the fixing rotator. A pressure rotator presses against the nip formation pad via the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. A heat generator is disposed inside the fixing rotator to heat the fixing rotator. A reflector is interposed between the heat generator and the nip formation pad. The reflector includes a reflection face to reflect radiant heat radiated from the heat generator. The reflection face includes a reflection portion disposed opposite the heat generator at various angles. A support is provided separately from the nip formation pad and supports the reflector.
