Patent number: 9658580Abstract: An image forming apparatus includes: a fixing portion for heat-fixing the image on a recording material; a duct including a suction port for sucking air from outside of the image forming apparatus and an exhaust port for delivering the air to the outside of the image forming apparatus; and a fan for forming a flow of the air from the suction port toward the exhaust port in the duct. The duct includes a merging portion, between the suction port and the exhaust port, for merging the air from the neighborhood of the fixing portion with the flow of the air by taking the air from the neighborhood of the fixing portion inside the duct. The recording material on which the image is fixed at the fixing portion is cooled by the air delivering through the exhaust port.Type: GrantFiled: October 30, 2014Date of Patent: May 23, 2017Assignee: Canon Kabushiki KaishaInventors: Shuji Saito, Naoto Tsuchihashi, Yoshisuke Kasuya

Patent number: 9599935Abstract: In an adjustment step, an adjustment purpose toner image is formed on an intermediate transfer belt, and the adjustment purpose toner image is removed from the intermediate transfer belt by a cleaning member contacting the intermediate transfer belt and through an electrostatic cleaning step. This adjustment step is executed in a state where a toner attachment amount on a charging member is switched from a first limit value, which is allowed in the image forming step to a second limit value, which is allowed immediately before executing the adjustment step. This switching is performed by the execution of a toner discharging step, where a power supply changes the state of applying voltage to the charging member from that in the electrostatic cleaning step, so that toner attached to the charging member is transferred to the intermediate transfer belt.Type: GrantFiled: January 27, 2016Date of Patent: March 21, 2017Assignee: Canon Kabushiki KaishaInventors: Masanori Asai, Kazuhiro Funatani, Hiroyuki Seki, Shuji Saito, Yasutaka Yagi, Tetsuichiro Fujimoto
