Patent number: 9789717Abstract: There is provided an image forming apparatus that can stably discharge liquid from a liquid discharge head and can be reduced in size by a simple structure. In an image forming apparatus, a gas compressor is provided so as to face the peripheral surface of an image forming drum , which corresponds to a range positioned outside a transport range in which a recording medium is transported and deviating from the transport range in a circumferential direction. The gas compressor is adapted to blow secondary compressed gas, which is generated by primary compressed gas supplied from the outside of the apparatus and of which the temperature is low, to the peripheral surface. The secondary compressed gas, which is blown from the gas compressor, is guided to the peripheral surface by a guide part and is diffused along the direction of a rotation axis of the image forming drum.Type: GrantFiled: February 28, 2017Date of Patent: October 17, 2017Assignee: FUJIFILM CorporationInventors: Yoshiyuki Tsuzawa, Naoya Okano

Publication number: 20050206074Abstract: When a sensor detects a leading end of a recording sheet, a movable distributing mechanism distributes the recording sheet to a first distributing position. When a sensor 50a detects the leading end of the recording sheet, the mechanism switches conveyer rollers and to the releasing position and returns them to the center position. Next, responding to that a sensor detects a trailing end of the recording sheet, the conveyer rollers and are reset to the nipping position and accept a second recording sheet. When the sensor detects a leading end of the recording sheet, the movable distributing mechanism distributes the second recording sheet to a second distributing position, opposite to the first distributing position. Rearward recording sheets are distributed alternately to the first and second positions.Type: ApplicationFiled: March 11, 2005Publication date: September 22, 2005Inventor: Yoshiyuki Tsuzawa
