    摘要: An image forming apparatus includes an image carrier; a transfer unit that transfers an image carried by the image carrier to a continuous medium; a fixing device including a first fixing member that contacts the continuous medium and heats the image transferred to the continuous medium and a second fixing member that is disposed so as to face the first fixing member with the continuous medium therebetween and presses the image, the fixing device fixing the image transferred to the continuous medium, the fixing device being configured so that the first fixing member and the second fixing member are capable of contacting or separating from each other; and a separation member that contacts the continuous medium and separates the continuous medium from the first fixing member when the first fixing member and the second fixing member separate from each other.

    摘要: The hole punching device includes rotary-to-reciprocating motion converters that convert rotational motion of a punch shaft connected to a punch motor into up-and-down motion of punch blades, and a short circuiting switch that short-circuits between terminals of the punch motor. The hole punching device further includes a braking current detector that detects braking current flowing through inter-terminal resistance of the punch motor, a braking current comparison unit that turns on the short circuiting switch once and compares a detected braking-current value detected by the braking current detector with a preset reference braking-current value, and a brake time determination unit that determines the time to turn on the short circuiting switch to apply a short circuit brake based on the comparison result obtained by the braking current comparison unit.
