Abstract: A developer supplying member is provided for supplying developer to a developer supporting member. The developer supplying member includes a foamed member having a discrete foam cell structure and being formed of a silicone rubber as a main component thereof. The foamed member constitutes a surface of the developer supplying member.

The foam cell wall has a ten-point average surface roughness between 45.2 ?m and 65.3 ?m.

Abstract: An image recording apparatus capable of correctly determining a color shift value between recording heads of different color. The image recording apparatus has each recording head print two types of patches as patterns on a conveyance belt and has a reflection intensity detection unit read reflection intensities of the two patches to determine the color shift value and correct the color shift value so as not to include a position shift value between a reference position and a position where the actual reading has started.
