IMAGE FORMING APPARATUS Russian patent published in 2012 - IPC G03G15/00 

FIELD: physics.

SUBSTANCE: image forming apparatus includes a transparent image forming device for forming an image on a sheet using transparent toner in a certain amount per unit area; a manual selector for selecting an image area in which the image is to be formed by transparent toner, and for selecting the amount per unit area; a heating device for heating the image formed by transparent toner on the sheet; a glossing device for processing the image formed by transparent toner on the sheet such that gloss becomes higher than that achieved with the heating device; a mode selector for selecting a first mode in which the glossing device is not used, and a second mode in which the glossing device is used; and a control device for controlling the amount of transparent toner per unit area in the image area such that said amount is less than the given amount in the second mode.

EFFECT: eliminating image defect in an area in which the image is formed by transparent toner in an amount per unit area which is less than a given amount.
