Conveying device, liquid applying apparatus, image forming apparatus, and post-processing apparatus

A conveying device comprising:

• a pair of rotary bodies including:
• a first rotary body disposed in a first region;
• and
• a second rotary body disposed in a second region and facing the first rotary body across a sheet conveyance passage through which a sheet applied with liquid is conveyed;
• a movable rotary body to contact an upstream side of the sheet from the pair of rotary bodies in a sheet conveyance direction while the sheet is held by the pair of rotary bodies;
• a sensor to detect the sheet;
• and
• processing circuitry configured to move the movable rotary body to change a position of the movable rotary body, in response to an output of the sensor.

• and
• a movable rotary body disposed upstream from the first rotary body in a sheet conveyance direction, the movable rotary body to move between the first region and the second region with respect to the sheet conveyance passage,
• the movable rotary body to move to the second region in a middle of conveyance of the sheet between the first rotary body and the second rotary body,
• wherein, when either a liquid applied area rate or an amount of liquid application on one face of the sheet is equal to or smaller than an opposite face of the sheet, an amount of movement of the movable rotary body to the second region is reduced or the movable rotary body is not caused to move to the second region.
