DEVICE FOR FORMING IMAGES Russian patent published in 2007 - IPC G03G15/16 

FIELD: image forming devices.

SUBSTANCE: device contains photo-sensitive substrate, from which toner image is transferred by means of primary transfer device to intermediate transferring substrate mounted with possible rotation, from which secondary transfer device performs secondary transfer of toner image to sheet. Device also contains control means, meant for controlling intermediate transferring substrate and secondary transfer means and for changing rotation speed of intermediate transferring substrate from first speed to second speed after completion of primary transfer, and also for determining in accordance to sheet size and number of images, simultaneously formed on the surface of intermediate transferring substrate, of possible change of rotation speed of intermediate transferring substrate before beginning of second transfer during its first turn during realization of primary transfer or during its second turn, which follows the first turn, when aforementioned primary transfer is realized, and also for changing rotation speed of intermediate transferring substrate immediately before beginning of secondary process.

EFFECT: increased productiveness due to decreased time period starting from moment, when first transfer is complete, ending at moment, when secondary transfer is started.
