Abstract:
An image-forming apparatus, comprising:a plurality of image-forming elements; a plurality of first driving motors, respectively corresponding to said image-forming elements, to drive said plurality of image-forming elements; an intermediate transfer element that is disposed opposite said plurality of image-forming elements; a second driving motor to drive said intermediate transfer element; and a controlling section to control said plurality of first driving motors and said second driving motor independently of each other; wherein said controlling section controls said plurality of first driving motors so as to unify peripheral speeds of said plurality of image-forming elements at a first peripheral speed; and wherein said controlling section controls at least one of said plurality of first driving motors and said second driving motor so that a second peripheral speed of said intermediate transfer element coincides with said first peripheral speed during a transition period in which said first peripheral speed changes from a certain peripheral speed to another peripheral speed.
