Description

上記目的を達成するための本発明の画像形成装置は、記録材に画像を形成する画像形成部と、記録材の搬送方向に直交する方向の記録材の幅を検知するセンサと、前記センサからの出力に基づいて記録材の搬送間隔を制御する制御部とを備え、前記制御部は、搬送された記録材の幅が前記センサで検知可能な記録材の幅より大きい場合は、前記搬送間隔を第１の搬送間隔に設定し、搬送された記録材の幅と前記センサによって検知可能な記録材の幅の差の値が予め設定された値以下の場合に、前記搬送間隔を前記第１の搬送間隔よりも大きい第２の搬送間隔に設定することを特徴とする。 In order to achieve the above object, an image forming apparatus of the present invention includes an image forming unit that forms an image on a recording material, a sensor that detects a width of the recording material in a direction orthogonal to the conveyance direction of the recording material, and the sensor. A control unit that controls the conveyance interval of the recording material based on the output of the recording material, and the control unit, when the width of the conveyed recording material is larger than the width of the recording material that can be detected by the sensor, Is set to the first conveyance interval, and the difference between the width of the conveyed recording material and the width of the recording material detectable by the sensor is equal to or smaller than a preset value, the conveyance interval is set to the first conveyance interval. The second conveyance interval is set to be greater than the conveyance interval.
