| 发明名称 | Image forming method | ||
| 摘要 | A plurality of image parts, each having a different gloss level, are formed on the same recording material by electrophotographic technology. The plurality of gloss levels are visually recognized due to the plurality of image parts. The image forming method includes: developing electrostatic latent images on respective image carriers using a high softening point clear toner and a low softening point clear toner, to form a toner image by the high softening point clear toner and a toner image by the low softening point clear toner; transferring the toner images onto a recording material; and heat-fixing the toner image for low gloss and the toner image for high gloss transferred and formed onto the recording material, wherein a softening point Tm(a) of the high softening point clear toner and a softening point Tm(b) of the low softening point clear toner satisfy Tm(a)−Tm(b)>6° C. | ||

| 主权项 | 1. An image forming method comprising: a developing step of developing an electrostatic latent image for a high softening point clear toner and an electrostatic latent image for a low softening point clear toner both being formed on an electrostatic latent image carrier, using a high softening point clear toner and a low softening point clear toner each having a different softening point, to form a toner image by the high softening point clear toner and a toner image by the low softening point clear toner; a transferring step of transferring the toner image by the high softening point clear toner and the toner image by the low softening point clear toner onto a recording material via an intermediate transfer body to form a toner image for low gloss and a toner image for high gloss; and a fixing step of collectively heat-fixing the toner image for low gloss and the toner image for high gloss on the recording material, wherein a softening point Tm(a) of the high softening point clear toner and a softening point Tm(b) of the low softening point clear toner satisfy a relational formula (1) below: Tm(a)−Tm(b)>6° C. Relational formula (1): | ||
