An intermediate transfer member including a base layer, wherein the base layer contains a thermoplastic resin and an electroconductive filler dispersed in the thermoplastic resin, and wherein the base layer has a volume resistivity of 110.sup.6 to 110.sup.13 .Math.cm, and the base layer has an electroconductive path index of 0.20 or less.
Endless belt, belt unit, and image forming apparatus
An endless belt includes a base material layer, the base material layer containing a polymer material and conductive particles, wherein in a section of the base material layer in a thickness direction, the conductive particles have an area ratio of 9.0% or more and 14.5% or less, an average value of areas of Delaunay triangles taking centers of gravity of the conductive particles as vertices is 0.10 m.sup.2 or more and 0.90 m.sup.2 or less, and a standard deviation of the areas is 0.010 m.sup.2 or more and 0.080 m.sup.2 or less.
Pressing device and image forming apparatus
A pressing device includes an intermediate transfer unit, a secondary transfer unit, a presser, and a drive transmitter. The intermediate transfer unit transfers and conveys a toner image. The secondary transfer unit faces the intermediate transfer unit to form a nip portion between the secondary transfer unit and the intermediate transfer unit and transfers the toner image onto a conveyed material at the nip portion. The presser applies a pressing force for pressing the secondary transfer unit to the intermediate transfer unit at the nip portion. The drive transmitter transmits the pressing force and a conveyance driving force to a driven transmitter of the secondary transfer unit, is restricted in position by the presser, and is movable together with the presser.

Belt device and image forming device
A belt device includes a cleaning unit having a cleaning member that abuts a belt and cleans a front surface of the belt. A tension roller includes a deviation suppression mechanism on one side of and in a width direction of the tension roller. The width direction intersects a transport direction of the belt. The deviation suppression mechanism suppresses deviation of the belt in the width direction by tilting a rotary shaft of the tension roller.
