| 1. An image-forming apparatus for forming a multi-color toner image by superimposing a plurality of colored toners, the image-forming
apparatus comprising:
an image-forming unit that forms a white toner image between a transfer material and the multi-color toner image by developing
and transferring white toner corresponding to the multi-color toner image; and
a fixing unit that fixes the multi-color toner image and the white toner image on the transfer material,
wherein a storage elastic modulus G′(T)(W) at a saturated temperature in a fixing nip of the white toner at a time of the fixing is higher than a storage elastic
modulus at a saturated temperature in the fixing nip of each of the colored toners at the time of the fixing, and
wherein the storage elastic modulus G′(T)(W) at the saturated temperature in the fixing nip of the white toner at the time of the fixing is 1.0×104 dyn/cm2 or more and 1.0×106 dyn/cm2 or less.
