Patent number: 10416597Abstract: An image forming apparatus, having a body, a fuser to fix an image on a recording medium by heat, an interface to accept a value for a first time, which is between an end of fixing by the fuser until entry into a low power-consuming condition for the heater, a fan, and a controller, is provided. The controller sets a second time being a predetermined length and subtract the second time from the first time to obtain a third time. If the third time is given a positive value, the controller continues driving the fan after the end of the fixing and throughout the third time, and inactivates the fan after the third time. If the third time is given a value smaller than or equal to zero, the controller inactivates the fan during the first time before the entry into the low power-consuming condition.Type: GrantFiled: October 11, 2018Date of Patent: September 17, 2019Assignee: Brother Kogyo Kabushiki KaishaInventors: Daisuke Ishizuka, Yuichi Ikeno, Atsushi Hayakawa
