Abstract: An image forming apparatus includes a brush member that includes a fiber yarn and that can come into contact with a surface of an image bearing member at a downstream of a transfer member and at an upstream of a charging member in a rotation direction of the image bearing member. The image bearing member and the brush member are relatively movable to a first position at which a leading end of the fiber yarn separates from the surface of the image bearing member, and a second position at which the leading end of the fiber yarn comes into contact with the surface of the image bearing member. A relative approaching direction of the brush member to the image bearing member upon relative movement from the first position to the second position is a direction from a downstream side to an upstream side in the rotation direction.

Abstract: A semiconductor module includes a lead including a first bonding portion and a coupling portion extending in a Y direction from the first bonding portion. The first bonding portion has a first width end, and a second width end connected to the coupling portion. The lead has first and second length sides opposite to each other in an X direction. The lead has in the X direction first and second widths at first and second positions, and the second position is away from the first position in the Y direction. In the plan view, the lead has a shape in which the first width is greater than the second width such that positions of the first and second length sides at the second position are respectively located inward in the X direction with respect to positions of the first and second length sides at the first position.
