Abstract
A developer accommodating unit includes: a developer accommodating member, provided with an opening for permitting discharge of a developer, for accommodating the developer; a sealing member including a connecting portion for being connected to the developer accommodating member so as to seal the opening; and an unsealing member for exposing the opening by moving the sealing member to peel the connecting portion from the developer accommodating member. The connecting portion includes a first connecting portion and a second connecting portion with respect to a longitudinal direction thereof. When the connecting portion is peeled from the developer accommodating member, the unsealing member is flexed so that the first connecting portion is peeled earlier than the second connecting portion.
