Abstract

Official abstract text for this publication.

An image forming apparatus includes a first roller and a second roller on which a recording medium is stretched; a head which performs image forming on the recording medium in an image forming region between the first roller and the second roller; an opening-shutting door which is provided in an external member; an opening-shutting regulation unit which regulates an opening operation of the opening-shutting door; and a control unit which transports the recording medium while applying a tension to the recording medium in the image forming region by controlling rotations of the first and second rollers, and regulates the opening operation of the opening-shutting door by the opening-shutting regulation unit while the head is performing the image forming, in which the control unit releases a regulation of the opening operation of the opening-shutting door by the opening-shutting regulation unit after performing a preparation operation for releasing the regulation which stops the recording medium in a state in which the tension is applied to the recording medium in the image forming region by controlling the rotations of the first and second rollers.
