摘要： An image forming unit includes an image bearing body, a developer bearing body that supplies a developer to the image bearing body, a developer storage portion for storing the developer, a developer reserving portion that reserves the developer, a replenishing member that replenishes the developer from the developer reserving portion to the developer storage portion, and a guide member provided between the replenishing member and the developer bearing body. The guide member temporarily holds the developer replenished by the replenishing member and regulates falling of the developer. A conveying member conveys the developer held by the guide member in an axial direction of the developer bearing body along the guide member. A detecting portion is provided between the guide member and the developer bearing body for detecting the developer. The replenishing member replenishes the developer to the developer storage portion based on a result of detection using the detecting portion.
