Abstract
A method of forming a drum assembly for use as a rotatable endless surface onto which a toner image is formed. The drum assembly has a hollow drum with an opening at each end and a surface onto which the image is formed. A support flange, having an aperture in the center thereof, is cooled before being inserted into each end opening. The drum assembly also includes a shaft having a collar fixed in the vicinity of each end. After the shaft is positioned inside the drum, the collars are positioned to coincide with the flange apertures. Screws secure each collar to its respective flange. The screws can be adjusted to reduce the eccentricity of the drum.
