Publication number: 20230251594Abstract: The fixing device includes: a fixing belt that is heated by a heater lamp; a pressure roller that makes contact with the fixing belt; a fixing pad that sandwiches the fixing belt from the inner side of the fixing belt and is arranged opposing the pressure roller, and which forms a nip portion between the fixing belt and the pressure roller; a sliding sheet provided between the fixing pad and the fixing belt, which reduces the frictional force with the fixing belt; and a pad heat transfer plate provided between the sliding sheet and the fixing pad, which adjusts the heat transfer in a longitudinal direction of the fixing belt. The fixing pad has protrusions and that make contact with the pad heat transfer plate, and forms a gap between the fixing pad and the pad heat transfer plate in a location where the protrusions and are not making contact.Type: ApplicationFiled: January 19, 2023Publication date: August 10, 2023Inventor: Kouta YOSHIKAWA

Patent number: 9170536Abstract: A fixing device is configured to move the pressure release member in predetermined movement directions relative to the support member such that the biasing member can function. The support member has a first retaining part. The pressure release member has a retention element to be held in the first retaining part of the support member. When the retention element is held in the first retaining part of the support member, the pressure release member is configured to apply a biasing force of the biasing member to the support member and thereby to cause the second fixing member to be pressed against the first fixing member.Type: GrantFiled: January 24, 2014Date of Patent: October 27, 2015Assignee: Sharp Kabushiki KaishaInventors: Kouta Yoshikawa, Masaya Asakawa
