摘要： A sheet transport device includes pre-transfer sheet-transport rollers that transport a sheet to a transfer position at which an unfixed image is transferred, the pre-transfer sheet-transport rollers including a first roller in which three or more separate rollers attached to a first shaft rotate, and a second roller in which three or more separate rollers attached to a second shaft are in contact with the separate rollers of the first roller and rotate. The hardness of an inner separate roller of the first roller is lower than the hardness of end separate rollers of the first roller. The outside diameter of an inner separate roller of the second roller is greater than the outside diameter of end separate rollers of the second roller.

摘要： A rotary arm restricts the rotation of a first sun gear or a second sun gear according to forward/reverse rotation drive of sheet discharge rollers. As a result, a rotating direction of a transmission gear coupled to the sheet discharge rollers is switched. If θ1A denotes a pressure angle of gear teeth of a gear portion of the first sun gear and θ2A denotes a pressure angle of gear teeth of a first planetary gear, a relationship of θ2A+0.5°≤θ1A≤θ2A+1.5° is satisfied.

摘要： A rotating member control device that controls a first rotating member and a second rotating member to convey a sheet includes a processor configured to execute a program to implement processes of controlling the first rotating member and the second rotating member to come into contact or be separated from each other and acquiring a value that corresponds to or is proportional to a driving torque of a first driving unit that rotationally drives the first rotating member. The processor acquires the value upon separation when the first rotating member and the second rotating member are separated from each other and upon conveyance when the sheet is held between and conveyed by the first rotating member and the second rotating member. The processor further sets a rotational speed of the second rotating member such that the value acquired upon separation and the value acquired upon conveyance become equal.

摘要： An image forming apparatus includes a casing; a process unit for forming a developer image on a sheet; an image exposing unit; a sheet cassette detachably mounted to the casing; a feeding roller for single the sheet from the cassette; a feeding guide provided in the casing and configured to guide the sheet moving from the cassette to the process unit. The exposing unit is disposed right above the feeding roller. The process unit is at a position the same position as the exposing unit in the vertical direction and downstream of the exposing unit in a horizontal direction. The cassette is below the feeding roller. The guide is between the exposing unit and the cassette in the vertical direction. The guide includes upper and lower guides. When the cassette is drawn out of the casing, the lower guide moves to an accommodating portion in the cassette.

摘要： An image forming apparatus includes a conveying path, a reverse path, a first guide member and a second guide member. The conveying path conveys a sheet to a discharge part. The reverse path conveys the sheet again to the image forming part. The first guide member is provided movably between a first closed position for forming the conveying path and a first opening position for opening the conveying path. The second guide member is provided movably between a second closed position for forming the reverse path and a second opening position for opening the reverse path. The first guide member contacts with the second guide member in a process of moving from the first closed position to the first opening position and moves the second guide member from the second closed position to the second opening position.
