SIZING DEGREE DETECTION DEVICE, SIZING DEGREE DETECTION METHOD, IMAGE FORMATION DEVICE, AND IMAGE FORMATION METHOD
Document Type and Number:
Japanese Patent JP2015108598
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sizing degree detection device capable of measuring sizing degree with no individual difference in measurement results.SOLUTION: A sizing degree detection device includes a discharge part 11 for making a droplet stick to a sheet material, a detection part 12 which, before and after the time point at which the droplet is made to stick to a sheet material SH by the discharge part 11, detects thermal conductivity of gas near the sticking part of the sheet material SH, and calculation means which, comparing with the thermal conductivity before sticking of the droplet which is detected by the detection part 12, acquires passage of time from the time point when the thermal conductivity after the sticking that is detected by the detection part 12 changes to be a predetermined ratio or higher, and acquires sizing degree of the sheet material SH based on a relationship between the passage of time and the sizing degree of the sheet material SH.
