<p><P>PROBLEM TO BE SOLVED: To provide a development device where a cleaning operation can be easily performed to the edges of a layer thickness regulation member and the circumference of a gap regulation member. <P>SOLUTION: A layer thickness regulation blade 6 arranged so as to be confronted with a development roller 3 is energized toward the development roller 3 with spring members 11. By depressing the layer thickness regulation blade 6 and compressing the spring members 11, a cleaning space C for a cleaning operation is formed between the development roller 3 and the layer thickness regulation blade 6. Further, gap regulation members 9 are fitted freely slidably to the side confronted with the development roller 3 in the layer thickness regulation blade 6. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
