- a nylon TAD24, manufactured by Toshiba Corporation
- the image forming sheet was visually inspected for a jagged defect (jagged transfer) caused by a feed roller, and evaluated according to the following criteria.
- Printing was performed continuously for 10 sheets, and the degree of paper feeding failure such as paper feeding failure or paper jam was evaluated based on the following criteria.
- the transferred image area was visually observed, and the washing resistance was evaluated according to the following criteria.
- the reflection color density (color density) of the solid yellow image area ( ⁇ ), magenta ( ⁇ ), cyan (C), black (B) is measured.
- the washing color density retention rate was calculated according to the following equation, and the average value was calculated.
- the yellow color density Y, magenta color density ⁇ , cyan color density C, black color density Table 1 also shows the color density B of the rack.
- Washing color density retention rate (density after washing) / (density before washing) X 100 (%)
- the printed image and the transferred image were immersed in water at 23 ° C. for 15 seconds, quickly pulled up, suspended and air-dried, visually observed for bleeding, and evaluated according to the following criteria.
- a sunset image was printed, the hue of the transferred image was visually observed, and evaluated based on the following criteria.
- the amount of benzyl chloride was measured using gas chromatography / mass spectrometry (GC / MS method) under the following conditions.
- benzyl chloride contained in the sheet was quantified. Furthermore, based on the quantitative results, the amount expected to be generated from 16 size A4 size image recording sheets was calculated, and the benzyl chloride concentration in the working space (volume: 10 m 3 ) was calculated. The molecular weight of benzyl chloride was 161.0, and the gas volume under standard conditions was 22.4 L.
