A holder for a long member includes: a holding member that includes a frame-shaped body portion; an anti-vibration member that includes a frame-shaped portion; and a fixing member that is provided with an insertion portion, and a flange. The anti-vibration member includes a pair of extension pieces that protrude in a state where the frame-shaped portion is inserted into the frame-shaped body portion, and that are sandwiched between the frame-shaped body portion and the flange when the insertion portion is inserted into the frame-shaped portion. Clearance is provided between an inner surface of a frame-shaped body portion side wall that faces a first wall in which the pair of extension pieces of the anti-vibration member are not provided in the frame-shaped body portion, and an outer edge of the flange facing the frame-shaped body portion side wall.

Holder for long member

A damper device includes a cylinder, a piston, a seal ring member, and a transmitting portion. The piston includes an annular outer circumferential portion, a first stopper portion, a second stopper portion, and a projecting portion. The projecting portion has an inclined surface which is inclined radially outwards form a side of the second stopper portion towards a side of the first stopper portion. The seal ring member is configured to allow a first chamber to communicate with a second chamber when a portion of the seal ring member which is not restricted by the first stopper portion is deformed in a direction away from the second stopper portion due to friction caused between the seal ring member and the cylinder or a fluid pressure from the second chamber to ride on the inclined surface.

Damper device

An image forming apparatus includes a control unit that controls each component, a first storage unit that is a non-volatile and rewritable storage unit mounted on the control unit, a toner containing unit that contains toner to be used for an image forming, a second storage unit that is a non-volatile and rewritable storage unit mounted on the toner containing unit, and a detecting unit that detects an amount of the toner remained in the toner containing unit. The control unit stores count information into the second storage unit, the count information is copied from the second storage unit to the first storage unit, when the detecting unit detects that the amount of the toner remained in the toner containing unit is not enough, and the count information is kept on being stored into the first storage unit, until the toner containing unit is replaced with a new one.
