Abstract
Official abstract text for this publication.
A transfer device includes an intermediate transfer belt, a driving roller, an environment sensor, a resistance detecting sensor, and a speed ratio adjusting section. The toner images are transferred from the plurality of image carriers onto a surface of the intermediate transfer belt in a superimposed manner. The driving roller circumferentially and rotationally drives the intermediate transfer belt. The environment sensor detects a temperature or a humidity around the intermediate transfer belt. The resistance detecting section detects a change in a resistance value of the intermediate transfer belt. The speed ratio adjusting section controls a rotation speed of the driving roller according to results of detection by the environment sensor and the resistance detecting section, thereby adjusting a speed ratio Vb/Vd between a circumferential rotating speed Vb of the intermediate transfer belt and a rotation speed Vd of the image carrier.
First claim
Opening claim text (preview).
The invention claimed is: 1. A transfer device comprising: an intermediate transfer belt disposed to face a plurality of image carriers each carrying a toner image on a circumferential surface of the image carrier and moreover rotationally driven at an equal speed, the intermediate transfer belt being circumferentially and rotationally driven in one direction, the toner images being transferred from the plurality of image carriers onto a surface of the intermediate transfer belt i…
