1. An image forming apparatus comprising:
a movable member unit including a movable member on which a toner image is carried or a movable member configured to feed a recording material on which the toner image is carried, wherein said movable member unit movably supports said movable member; and a container connectable with said movable member unit and including a cleaning member, a sheet member and an urging member, wherein said cleaning member removes a toner on said movable member with movement of said movable member in contact with said movable member in a state in which said movable member unit and said container are connected with each other, wherein said sheet member extends in a widthwise direction perpendicular to a movement direction of said movable member and is supported by said container in one end side thereof with respect to the movement direction of said movable member, and at least during cleaning of said movable member, a part of said sheet member in the other end side where a free end of said sheet member is positioned in a first state in which the part of said sheet member contacts said movable member codirectionally with the movement direction of said movable member, wherein said urging member is adjacent to said sheet member in an upstream side of said sheet member with respect to the movement direction of said movable member and is disposed at a position overlapping with neighborhoods of ends of said sheet members with respect to the widthwise direction, and the part of said sheet member in the other side where the free end of said sheet member is positioned is in a second state in which the part of said sheet member is sandwiched between said movable member and said urging member counterdirectionally with the movement direction of said movable member when said movable member unit and said container are connected with each other, and wherein when a friction coefficient between said sheet member and said movable member is μ1 and a friction coefficient between said sheet member and said urging member is μ2, the following relationship is satisfied:
μ2>μ2. |
