  • Publication number: 20190018359
    Abstract: An image forming apparatus includes a conveying unit, transfer unit, a loop detecting unit, a driving source, a control unit, and a measuring unit. The transfer unit transfers an image formed on an image bearing member to the printing material conveyed by the conveying unit driven by the driving source. The loop detecting unit detects an amount of a loop formed in the printing material between the conveying and transfer units. The control unit changes a rotational speed of the driving source based on the detection result. The measuring unit measures a rotation amount of the driving source while a first printing material is conveyed by both of the conveying and transfer units. The control unit controls the rotational speed of the driving source based on the measured rotation amount so that a leading end of a second printing material reaches the transfer unit per the image bearing member image.

  • Patent number: 9342000
    Abstract: An image-forming apparatus supplies power to a heater at the smaller duty ratio of: an upper-limit duty ratio which is set according to the current detected by an inlet current detecting unit in a warm-up period of a fixing unit; and a duty ratio which is continuously corrected according to a change in a heater resistance value and is required for supplying a predetermined target power to the heater. By this arrangement, the image-forming apparatus can output a first page of recording material in a short period time so that a current consumption of the entire apparatus does not exceed rated current consumption.
