Patent ID: 7384042

Claim:
An image forming device comprising: a recording unit that forms an image on a recording medium; a transport mechanism that transports the recording medium in a first direction, the transport mechanism including a first transport member disposed on an upstream side of the recording unit with respect to the first direction and a second transport member disposed on a downstream side of the recording unit with respect to the first direction; a sensor that detects a trailing edge of the recording medium transported by the transport mechanism; and a controller that controls the first transport member and the second transport member to perform a transport operation, wherein: the controller controls the second transport member to transport the recording medium at different speeds between before and after the trailing edge of the recording medium passes by the first transport member, the controller controls in alternation the recording unit to perform a print operation and the transport mechanism to perform the transport operation, the recording unit forms a predetermined width of the image on the recording medium during a single print operation while moving in a second direction orthogonal to the first direction, the transport mechanism transports the recording medium toward the first direction by a predetermined distance during a single transport operation regardless of whether the trailing edge of the recording medium has passed by the first transport member, the first transport member includes a pair of rollers that transport the recording medium while nipping the recording medium between them, the controller controls the transport mechanism to transport the recording medium at a first speed before the trailing edge of the recording medium is released from being nipped between the pair of rollers, at a second speed when the trailing edge of the recording medium is being released from being nipped between the pair of rollers, the second speed being slower than the first speed, and at a third speed after the trailing edge of the recording medium is released from being nipped between the pair of rollers, the third speed being faster than the second speed and slower than the first speed.
