Abstract: A document conveyance apparatus includes a first conveyance path, a first image reading part, a second conveyance path, a third conveyance path and a branch guide. The first conveyance path extends linearly. The first image reading part reads an image on one face of the document conveyed along the first conveyance path. The second conveyance path branches from the first conveyance path at a branch point on a downstream side of the first reading part in a conveyance direction of the document and is formed to be curved. The third conveyance path branches from the first conveyance path at the branch point and extends linearly in a same extending direction as an extending direction of the first conveyance path. The branch guide is provided at the branch point and guides the document to the second conveyance path or to the third conveyance path.

Abstract: A transfer unit includes a transfer belt, transfer rollers, support members, moving members, a pinion gear, a sensor, and a light shielding plate that blocks or opens an optical path of the detection portion by rotation of a gear transmitting the drive force to the pinion gear. The light shielding plate includes a pulse portion in which a plurality of slits are formed, and at least one of a light shielding portion and a light transmitting portion formed adjacent to the pulse portion. A rotation amount of the gear is detected based on the number of the slits of the pulse portion that has passed the detection portion, and a reference position of the gear is detected based on timing when an edge of the light shielding portion blocks the detection portion or timing when an edge of the light transmitting portion opens the optical path of the detection portion.

Abstract: A document conveying device according to the present disclosure includes a sheet feeding tray, a discharge tray, a feeding roller, a first lifting mechanism, a conveying mechanism, a support member and a second mechanism. On the sheet feeding tray, a document is stacked. The discharge tray is provided below the sheet feeding tray. The feeding roller feeds the document on the sheet feeding tray. The first lifting mechanism supports both end portions of the sheet feeding tray in a width direction intersecting a conveying direction of the document, and lifts and lowers the sheet feeding tray such that an upper surface of the document comes in contact with the feeding roller. The support member supports the sheet feeding feed tray on an upstream side of the first lifting mechanism in the conveying direction. The second lifting mechanism lifts and lowers the support member in synchronization with the sheet feeding tray.

Abstract: An image forming apparatus includes an intermediate transfer belt, an image forming device, a brush roller, a bias application device, and a controller. The bias application device applies, between the intermediate transfer belt and the brush roller, a bias for shifting a charged residual toner from the intermediate transfer belt to the brush roller. The controller controls, in a period in which calibration or maintenance is executed, the bias application device to set an application amount of the bias at a predefined first value only in a specified time zone in which the residual toner is present on the intermediate transfer belt and to set the application amount of the bias at a predefined second value smaller than the first value in time zones other than the specified time zone.

Abstract: Provided is a document conveying apparatus that properly discharges documents regardless of the amount of documents stacked on a discharge tray without complicated construction of a transmission mechanism for transmitting a driving force to conveying rollers. A conveying roller pair is provided at an end portion on an upstream side. A swing mechanism swings a discharge mechanism centered around a drive shaft of the conveying roller pair. An upper surface height measuring unit measures the height of the upper surface of documents stacked on the discharge tray. A control unit, by causing the swing mechanism to swing the discharge mechanism according to the height measured by the upper surface height measuring unit, performs control so that the difference between a discharge port and the upper surface of the documents stacked on the discharge tray is within a specified range.
