Publication number: 20130183058Abstract: An image forming apparatus includes a main body having an opening, and a consumable article separably installed in the main body through the opening. The consumable article includes a connector to perform a connection. The main body includes a connection terminal protruding toward the connector and a guide protrusion to prevent the connection terminal from coming into contact with a portion adjacent to the connector. The consumable article is provided with a guide groove into which the guide protrusion is inserted when the connection terminal and the connector are positioned to correspond to each other. When the connection terminal and the connector reach positions corresponding to each other, the guide protrusion is into the guide groove to perform the connection between the connection terminal and the connector, which prevents friction between the connection terminal and a portion adjacent to the connector.Type: ApplicationFiled: January 14, 2013Publication date: July 18, 2013Applicant: Samsung Electronics Co., Ltd.Inventor: Jung Yun WON
