摘要： In a beltless tandem-type image forming apparatus of the invention, 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. 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.
摘要翻译：在本发明的无带式串联型图像形成装置中，沿着纸张的输送方向间隔地并排设置多对转印辊。控制部分依次通过由驱动部分驱动的各对转印辊的辊隙部分顺序地输送纸张，同时顺序地将由成像部分形成的图像转印到纸张上。由驱动部控制的各对转印辊的输送速度，对于每对转印辊，沿着纸张的输送方向从上游侧向下游侧逐渐降低，因此，驱动各对的驱动期间沿着纸张的输送方向从上游侧向下游侧的每对转印辊逐渐增加用于输送每张纸的转印辊。控制部进行控制，使得成像部的成像周期与驱动部在每对转印辊中的驱动期间同步。

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： A plurality of first viscoelastic bodies are disposed in insertion holes of a first rotary member. A plurality of second viscoelastic bodies are disposed in guide holes of a second rotary member. Each of the first and the second viscoelastic bodies has an elastic coefficient changing in accordance with aging due to use. A guide member moves a contact member along the insertion hole and the guide hole. The contact member applies a compressive load to the first viscoelastic body. The aging of the second viscoelastic body due to the compressive load applied thereto moves a position of the first viscoelastic body where the compressive load is received from the contact member toward a farther side from a rotational shaft side.
