Pressing device and pressing process apparatus using the same

A pressing device comprising:

• a first pressurization unit, wherein the first pressurization unit is a pressurization roll;
• a second pressurization unit that is provided to face the first pressurization unit, and sandwiches and pressurizes a medium moving in a contact region formed between the first pressurization unit and the second pressurization unit, wherein the second pressurization unit is a pressing member;
• a contact region variable unit that changes a width dimension of the contact region along a moving direction of the medium in a state of maintaining a contact pressure on an outlet side of the contact region, in varying a contact state of the contact region, wherein the contact region variable unit comprises a motor;
• and
• a medium guide unit that is provided on an upstream side of the contact region in the moving direction of the medium, and guides the medium in accordance with an inlet portion of the contact region which is changed by the contact region variable unit, wherein the medium guide unit comprises a guide chute,
• wherein the contact pressure on the outlet side of the contact region remains unchanged as the contact state of the contact region varies.
