Abstract
Developing cartridge includes doctor blade in contact with developer carrying member. The doctor blade includes supporting plate having proximal end portion and distal end portion. Pressing portion is provided on the distal end portion to define contacting portion at which the doctor blade contacts surface of the developer carrying member. The pressing portion has end face extending in a direction away from the developer carrying member from the contacting portion and facing an upstream side in rotational direction of the developer carrying member. The proximal end portion is positioned downstream from the contacting portion in the rotational direction of the developer carrying member. Angle α between the end face and a plane tangent to the contacting portion, at a position in proximity to the developer carrying member, is not smaller than 90 degrees, as viewed in cross section orthogonal to axis of rotation of the developer carrying member.
