TREATMENT-TARGET MODIFICATION DEVICE, TREATMENT-TARGET MODIFICATION SYSTEM, IMAGE FORMING SYSTEM, AND IMAGE FORMING METHOD

摘要

A treatment-target modification device is configured to modify a treatment target (20) being conveyed, with discharge. The treatment-target modification device includes: a hydrophilization unit (100) configured to perform hydrophilization treatment on the treatment target (20); and a measurement unit configured to measure two-dimensional distribution of a reflectance spectrum of light reflected from the hydrophilization-treated treatment target (20).
