摘要： An endless belt device includes an endless belt and a plurality of rotary members rotatably supporting the endless belt. One of the plurality of rotary members includes a marker formed on a part of a circumferential surface of a rotation axis thereof. A reflection-type sensor is arranged to oppose the circumferential surface of the rotation axis of the one of the plurality of rotary members to detect the marker formed on the circumferential surface. A rotation speed of the endless belt is detected by detecting the marker on the circumferential surface of the rotation axis of the one of the plurality of rotary members by the reflection-type sensor.

摘要： A cleaning apparatus is for removing a toner from a surface of an endless belt. The cleaning apparatus includes a blade, a blade holding structure, and an abutment maintaining structure. The blade abuts on the endless belt that is supported on a tension roller. The blade holding structure holds the blade with its rotation restricted, in a movable manner in the direction of motion adjustment to adjust tension on the endless belt, and causes the blade to abut on a winding area of the endless belt with respect to the tension roller. The abutment maintaining structure allows the blade to follow up movement of the tension roller to thereby maintain abutment of the blade on the endless belt.

摘要： In an image forming apparatus of the type sequentially executing charging, exposure, development and image transfer, a device for applying a lubricant to the surface of an image carrier includes a lubricant applying member rotatable in contact with the image carrier for applying, at a position where the lubricant applying member contacts the image carrier, the lubricant to the surface of the image carrier while deforming its contour in accordance with a bite of the surface of the image carrier. A lubricant feeding unit feeds the lubricant to the lubricant applying member and includes a lubricant providing unit having a preselected thickness t. The surface of the image carrier bites into the lubricant applying member by an amount T while the lubricant providing unit bites into the lubricant applying member by an amount t' smaller than the amount T, but substantially equal to or slightly greater than the thickness t. The device has a low cost, compact configuration and can use up the lubricant without any waste while desirably applying it to the image carrier.
