Title:
転写ベルト清掃機能付き画像形成装置
Document Type and Number:
Japanese Patent JP4560571
Kind Code:
B2
Abstract:
To provide an image forming apparatus which can prevent malfunction of the open/close control of a shutter due to erroneous detection of the toner on the transfer belt when the opening and closing of the shutter is detected from the output from an optical sensor. The separation/contact assembly for moving a cleaning member into and out of contact includes an arm rotationally supported on a pivot, an abutment part fixed to the body frame so as to limit the rotation of the arm and a spring for pressing the arm in the clockwise direction. The cleaning member is attached at the distal end of the arm. The cleaning member cleans the transfer belt surface when the shutter is closed, so that the cleaned transfer belt surface can be always detected when the shutter is open.
