Publication number: 20240094671Abstract: An image forming apparatus includes a fixing device to heat a recording material at a use position, an opening and closing member, and a drawer unit. In a state where the fixing device is at the use position, part of the fixing device is located in a space for the drawer unit to pass through when moved from a first inner position to a first outer position so that movement of the drawer unit from the first inner to the first outer position is restricted. The fixing device is retracted from the use position to a retracted position so that the movement of the drawer unit from the first inner to the first outer position is allowed. Part of the fixing device at the retracted position is at a position higher than a position of an upper cover portion of the opening and closing member at a closed position.Type: ApplicationFiled: September 11, 2023Publication date: March 21, 2024Inventors: CHIKARA IMAIZUMI, SATOSHI MURASAKI, KIYOSHI FURUTA, SHINYA NODA, KUNIHIRO NIWA, YOJI MISAO, TOMOOKU KOYAMA, TOMOKI KATAFUCHI, TOMONARI INOUE, KOICHI SEKIMIZU

Publication number: 20240085825Abstract: An image forming apparatus to form an image on a recording material includes an apparatus main body having a first end provided with an opening and having a second end, a fixing device to heat the recording material, an opening and closing member, a drawer unit having a first photosensitive drum, and a transfer device. When being moved from a first inner position inside the apparatus main body to a first outer position outside the apparatus main body through the main body opening, the drawer unit is to be moved in a moving direction intersecting with a rotation axis of the first photosensitive drum, and is to be moved away from the second end. When being moved from a second inner position inside the apparatus main body to a second outer position outside the apparatus main body, the transfer device is moved away from the second end.Type: ApplicationFiled: September 12, 2023Publication date: March 14, 2024Inventors: CHIKARA IMAIZUMI, SATOSHI MURASAKI, KIYOSHI FURUTA, SHINYA NODA, KUNIHIRO NIWA, YOJI MISAO, TOMOOKU KOYAMA, TOMOKI KATAFUCHI, TOMONARI INOUE, KOICHI SEKIMIZU

Publication number: 20240085824Abstract: An image forming apparatus includes an apparatus main body, a drawer unit, and a transfer device a including a belt. When image formation on a recording material is performed, the drawer unit is at a first apparatus main body inner position and the transfer device is at a second apparatus main body inner position. In this drawer unit state, (a) a part of the transfer device is disposed downstream of the drawer unit in a moving direction in which the drawer unit moves from the first inner position to a first apparatus main body outer position, and (b) in a vertical direction, an area where the part of the transfer device is positioned overlaps, at least in part, with an area where the drawer unit is positioned. The transfer device includes a cleaning member to clean the belt and is accommodated in the part of the transfer device.Type: ApplicationFiled: September 12, 2023Publication date: March 14, 2024Inventors: CHIKARA IMAIZUMI, SATOSHI MURASAKI, KIYOSHI FURUTA, SHINYA NODA, KUNIHIRO NIWA, YOJI MISAO, TOMOOKU KOYAMA, TOMOKI KATAFUCHI, TOMONARI INOUE, KOICHI SEKIMIZU

Publication number: 20240085849Abstract: An image forming apparatus includes an apparatus main body, a drawer unit, and a transfer device including a belt. The drawer unit includes a first cartridge, a support member to which the first cartridge is detachably attached, and a first photosensitive drum disposed on the support member or the first cartridge. The drawer unit is moved to a first inner position inside the apparatus main body and to a first outer position outside the apparatus main body. The transfer device is moved to a second inner position inside the apparatus main body and to a second outer position outside the apparatus main body. The belt contacts the first photosensitive drum with the transfer device at the second inner position. The transfer device is moved from the second inner to the second outer position when the drawer unit is moved from the first inner to the first outer position.Type: ApplicationFiled: September 12, 2023Publication date: March 14, 2024Inventors: CHIKARA IMAIZUMI, SATOSHI MURASAKI, KIYOSHI FURUTA, SHINYA NODA, KUNIHIRO NIWA, YOJI MISAO, TOMOOKU KOYAMA, TOMOKI KATAFUCHI, TOMONARI INOUE, KOICHI SEKIMIZU

Patent number: 5027077Abstract: A humidity sensing apparatus which includes a humidity sensor which detects humidity as a function of impedance is provided. A reference resistor has a predetermined resistance value. A charge switching circuit selectively couples one of the reference resistor or the humidity sensor in series with a reference capacitor which has a predetermined capacitance. A voltage judging circuit determines whether the terminal voltage of the reference capacitor is high or low. A charge/discharge switch selectively charges and discharges the reference capacitor in accordance with the output of the voltage judging circuit. A sensor direction switching circuit inverts the direction of current flowing through the humidity sensor during charging of the reference capacitor. An oscillation frequency counter counts the number of charge/discharge cycles which are repeated during a predetermined time period.Type: GrantFiled: August 22, 1989Date of Patent: June 25, 1991Assignee: Seiko Epson CorporationInventors: Michio Yanagisawa, Masahisa Ikejiri, Hajime Miyazaki, Tsukasa Muranaka, Kunihiro Inoue, Shouichi Uchiyama
