Patent number: 11782373Abstract: An image forming apparatus for forming an image on paper includes a body surface temperature measuring sensor, a user interface, a communication interface, and a controller. The body surface temperature measuring sensor measures the body surface temperature of the operator in a non-contact manner. The user interface presents a message to the operator. The communication interface transmits a message to the administrator who manages the image forming apparatus. When access to the surface or the inside of the image forming apparatus is required and the body surface temperature of the operator is equal to or higher than a threshold temperature, the controller transmits a message requesting to touch the surface or the inside of the image forming apparatus to the administrator by the communication interface and presents a message requesting not to touch the image forming apparatus to the operator by the user interface.Type: GrantFiled: January 7, 2022Date of Patent: October 10, 2023Assignee: TOSHIBA TEC KABUSHIKI KAISHAInventor: Tetsuo Kato
