20150360893 | IMAGE FORMING APPARATUS - An image forming apparatus includes a feeder unit, a separating unit, a conveying unit disposed downstream of the separating unit in a sheet feeding direction, an image forming unit disposed downstream of the conveying unit in the sheet feeding direction, a drive unit, and a control unit. The feeder unit feeds a sheet. The separating unit separates sheets fed by the feeder unit one by one. The conveying unit conveys the sheet. The image forming unit forms, while the sheet is being conveyed, an image on the sheet. The drive unit drives the conveying unit. The control unit controls the drive unit. After the conveyed sheet reaches the image forming unit, the control unit reduces a conveyance speed of the sheet conveyed by the conveying unit. | 12-17-2015 |
20160033919 | IMAGE FORMING APPARATUS - An image forming apparatus includes a guiding part, a discharge flow path and an airflow control mechanism. The guiding part is configured to form a sheet conveying path from a sheet feeding part to a transferring device between a development unit and the transferring device. The discharge flow path formed between the development unit and the guiding part communicates with a sheet feeding part-side space where the sheet conveying path faces the sheet feeding part and an image carrier-side space where the sheet conveying path faces the image carrier. The airflow control mechanism is configured to guide airflow generated in the sheet feeding part-side space when a rear end of the sheet is separated from the sheet feeding part in a direction spaced away from a developing nip. | 02-04-2016 |
20160061295 | Image Forming Apparatus - An image forming apparatus including a driving source, a planetary gear mechanism including first, second and third elements, a rotation restraint member configured to switch the planetary gear mechanism between a locked state where rotation of the second element is locked and a released state where the second element is capable of rotating, and a switching mechanism configured to switch the planetary gear mechanism between a first state where any two elements of the first, second and third elements are separated and a second state where the two elements are coupled, wherein the third element is configured to rotate in a first direction when the planetary gear mechanism is in the locked state and first state and to rotate in a second direction opposite to the first direction when the planetary gear mechanism is in the released state and second state. | 03-03-2016 |
20160090251 | ELECTROSTATIC ADSORPTIVE BELT AND METHOD OF MANUFACTURING THEREOF, ASSEMBLY, AND CONVEYANCE SYSTEM - There is provided with a method of manufacturing an electrostatic adsorptive belt. A portion for forming an electrode pattern on a first resin layer is irradiated with an ultraviolet laser beam. A region including the portion for forming the electrode pattern on the first resin layer is oxidated. The electrode pattern if formed on the first region layer by plating. A second resin layer is formed on a surface of the first resin layer on which the electrode pattern is formed. | 03-31-2016 |
