【解決課題】 部品点数の増加に伴うコストアップや装 置の外観が変わるのを防止しつつ、特に、装置本体の一 側面近傍に転写用紙の搬送手段等を配設した場合でも、 駆動系の駆動音や搬送手段の送音が外部に漏れるのを効 果的に防止可能な画像形成装置を提供することを課題と する。
【解決手段】 本体カバーに送風等のために開口部を設 け、当該開口部を装置本体に対して開閉可能な用紙載置 部材が閉状態のときに覆うように構成して課題を解決し た。
PROBLEM TO BE SOLVED: To prevent the driving noise of a driving system and the noise of a carrying means from leaking to the outside while preventing the increase of the cost due to the increase of the number of parts and the change of appearance of a device by covering an opening part provided in a main body cover when an openable/closable paper loading member is closed with respect to a device main body. SOLUTION: On one side surface of an image forming device, a manual feeding tray 30 for supplying a transfer material different from a normal transfer paper in size and paper quality, to form a desired image on the transfer material is provided. The manual feeding tray 30 is formed to be longer than a conventional manual feeding tray 30 so that the top end part 30a of the manual feeding tray 30 has almost the same height as that of the top end part of the main body cover of the image forming device main body in the closed state of the tray 30. Sidewalls 30b are projectingly provided in both end parts in the width direction of the tray 30 to be abutted on the outside cover of the image forming device in the closed state of the tray 30, so that the noise leaking from the image forming device main body to the outside is prevented from leaking sidewards.
