Abstract: A developer transporting mechanism includes a pipe-like transporting path, sealing member, shutter, and urging member. The pipe-like transporting path, through which a developer is transported, has an discharge port at part of its side surface. The shutter is slidable along the surface of the sealing member to open and close the discharge port. The urging member urges the shutter in a direction in which the discharge port is closed. The sealing member is secured to the outer circumferential surface of the pipe-like transporting path. The sealing member also has a reduced part; its dimension in a width direction orthogonal to a direction in which the shutter moves is gradually reduced from the upstream end in the closing direction of the shutter toward the downstream end.

Abstract: An image forming apparatus includes a connection mechanism in electrical contact with a contact. The connection mechanism includes a terminal member, a power supplying member, an insulating member, and a holding member. The terminal member makes contact with the contact. The power supplying member feeds electric power to the contact via the terminal member and urges the terminal member toward the contact. The insulating member covers the terminal member. The holding member holds the terminal member covered with the insulating member. The terminal member, at a tip end portion of it that projects from the holding member, makes contact with the contact. The insulating member covers at least an entire region, except a contact portion with the contact, of the terminal member that projects from the holding member.

Abstract: A development device includes a rotational member and a housing. The housing includes a lower housing and an upper housing. The lower housing has an opened upper face. The upper housing has an opened lower face. A first edge portion around the opened upper face has a recess, a first contact face and a first opposite face. The first contact face is formed inside the recess. The first opposite face is formed outside the recess. A second edge portion around the opened lower face has a protrusion, a second contact face and a second opposite face. The protrusion is fitted into the recess. The second contact face comes into contact with the first contact face. The second opposite face opposes the first opposite face. The first and second contact faces are higher than the first and second opposite faces. The recess and the protrusion are adhered with an adhesive.

Abstract: A waste toner collecting device includes an intermediate collection box, a conveying path, a conveying screw, an exhaust path and a floating toner collection chamber. The conveying path is provided in the intermediate collection box. The conveying screw is rotatable in the conveying path. Through the exhaust path, air containing a floating toner is sucked and passed. The floating toner collection chamber is provided on a part of the exhaust path in the intermediate collection box. The floating toner collection chamber has a discharge opening opened to an inside of the intermediate collection box and a discharge door. Rotation of the conveying screw in a normal direction turns the discharge door into a storage position where the discharge opening is closed. Rotation of the conveying screw in a reverse direction turns the discharge door into a discharge position where the discharge opening is opened.

Abstract: A waste toner transporting device includes a waste toner passing passage, a waste toner collection container, a suction passage, a suction device, and a passing passage box. Through the waste toner passing passage, waste toner passes. The waste toner collection container collects the waste toner having passed through the waste toner passing passage. In the suction passage, suspended toner is sucked along with air inside a developing device. The suction device sucks the air inside the suction passage. Inside the passing passage box, the waste toner passing passage constituting part of the waste toner passing passage is formed. The suction passage constituting part of the suction passage is formed inside the passing passage box so as to be connected to the waste toner passing passage.
