Abstract
A method for adjusting a length of a doctor gap of a development device which is employable within an electrophotographic printer. The doctor gap is formed between a circumferential surface of a development roller and an extreme edge of a doctor blade that is arranged to be movable along a radius direction of the development roller. A dummy member, including a circle-shaped part whose radius value is a sum of a radius value of a development roller and the doctor gap is mounted in the development device. A position of the doctor blade along the radius direction is adjusted and fixed at a position at which the doctor blade and the circle-shaped part of the dummy member are in contact with each other. The dummy member is then removed from the development device. Thus, it becomes possible to accurately set a doctor gap with a simple structure, and the outer circumferential surface of the development roller is not scratched.
