摘要： In a beltless tandem-type image forming apparatus, a plurality of pairs of transfer rollers are placed side by side at intervals along a conveying direction of sheets. A control section independently conveys sheets in sequence through nip sections of respective pairs of transfer rollers driven by a driving section while sequentially transferring images formed by an imaging section onto the sheets. Conveying speeds of the respective pairs of transfer rollers controlled by the driving section are gradually decreased for every pair of transfer rollers from an upstream side toward a downstream side along a conveying direction of the sheets, and consequently, a driving period for driving the respective pairs of transfer rollers to convey each sheet is gradually increased for every pair of transfer rollers from the upstream side toward the downstream side along the conveying direction of the sheets.

Conveying speeds of the respective pairs of transfer rollers controlled by the driving section are gradually decreased for every pair of transfer rollers from an upstream side toward a downstream side along a conveying direction of the sheets, and consequently, a driving period for driving the respective pairs of transfer rollers to convey each sheet is gradually increased for every pair of transfer rollers from the upstream side toward the downstream side along the conveying direction of the sheets. The control section performs control so that an imaging period by the imaging section is synchronized with a driving period by the driving section in every pair of transfer rollers.

摘要： A fusing apparatus allows a recording member to pass through between a heat member and a pressure member, to transport and heat the recording member, and thereby fuses a toner image on the recording member. The heat member has a release layer, a low emissivity member, and an elastic layer. The release layer is formed on an outermost layer of the heat member. The low emissivity member is provided between the heat source and the release layer so as to abut on the release layer, and is made of a material with a lower emissivity than a material forming the release layer. The elastic layer is provided between the heat source and the low emissivity member. The release layer has infrared transmission properties at wavelengths of 2 to 10 μm.

摘要： In an image forming apparatus, a frame as an interior member is provided so as to oppose an exterior cover as an exterior member for controlling noise from an apparatus main body. An opening that is made up of a number of aperture regions is provided for allowing sound that is radiated to the exterior cover and reflected, to transmit toward the apparatus main body. By providing an opening in the frame or the like, it is possible to reduce noise energy radiated outside the apparatus in a simple manner.
