摘要： An image formation device is provided with an endless belt wound around a driving roller and a driven roller, a driving helical gear integrally provided at an axial end of the driving roller and rotating integrally with the driving roller. The driving helical gear applies a rotational force and an axial force to the driving roller. A plurality of guiding ribs are provided to an inner surface of the endless belt, while a regulating portion is provided at least one of the driving roller and the driven roller. The regulating portion has a regulation surface. When the endless belt moves obliquely in a direction in which the driving helical gear applies the axial force to the driving roller, side surfaces of the guiding ribs contact the regulating surface and prevent the oblique movement of the endless belt.

摘要： PROBLEM TO BE SOLVED: To achieve a structure which can prevent deterioration of belt shift control accuracy caused by the existence of a level difference of a width-direction end (edge) of an intermediate transfer belt 606.SOLUTION: A reference mark 3 is provided on the inner peripheral surface of an intermediate transfer belt 606 so as to stride over a level difference. When a rotational direction rear end of the reference mark 3 is detected by a reference detection sensor 2, an edge detection sensor 1 starts to detect an edge at a set sampling period. The sampling period Ts is set so as to satisfy L1≤V×Ts and L2=K×(V×Ts), wherein L1 is a length in a circumferential direction of the reference mark 3; V is a rotational speed of the intermediate transfer belt 606; L2 is a length in a circumferential direction from the reference detection sensor 2 to the edge detection sensor 1; and K is a natural number. As a result, the edge detection sensor 1 does not detect the level difference, so that belt shift control can be performed with high accuracy.

摘要： PROBLEM TO BE SOLVED: To restrain defective cleaning in a belt conveyer of cleaning a belt surface by a blade abutting on the belt surface.
SOLUTION: This intermediate transfer device 6 includes a plurality of rollers including a driven roller 63, an intermediate transfer belt 61 laid onto the plurality of rollers, and a meandering restraining guide 66 formed in the intermediate transfer belt 61. The intermediate transfer belt 61 is circulated by rotation of the plurality of rollers, and is constituted to bring an outer circumferential face into contact with the cleaning blade 65a. The meandering restraining guide 66 is formed in a protruded area 61a of the intermediate transfer belt 61, and restrains the intermediate transfer belt 61 from meandering, by abutting on an end face 63c of the driven roller 63. The end face 63c of the driven roller 63 is formed with a protruded part 63d and a groove part 63e circulated around the periphery of a rotation axis following the rotation of the driven roller 63.

摘要： PROBLEM TO BE SOLVED: To provide apparatus and method for steering a belt, having a transmission means including a rotatable part operatively connected to a rotatable element and having a diameter smaller than that of a steering roller. SOLUTION: This apparatus for steering a belt includes: the steering roller supporting the belt, the rotatable element and the transmission means.

The rotatable element is rotatable about a third axis, and the third axis is parallel to the first axis. The transmission means is disposed to convert a rotational motion of the rotatable element about the third axis into a pivoting motion of the steering roller about the second axis. The rotatable element is rotatable by a frictional force between a side portion of the belt and the rotatable element. COPYRIGHT: (C)2009,JPO&INPIT
