Image forming apparatus

An image forming apparatus comprising:

• an image bearing member;
• a developer bearing member configured to develop an electrostatic latent image formed on the image bearing member as an image using a developer;
• a frame configured to support the developer bearing member and including a storage member for storing the developer, where the stored developer is to be supplied to the developer bearing member;
• a transfer unit configured to transfer the developed image onto a recording material;
• a fixing unit configured to fix the image to the recording material and including a heater having a substrate on which a heating element is arranged;
• a first temperature detection unit configured to detect a temperature of the fixing unit;
• and
• a control unit configured to, based on a result of detection by the first temperature detection unit, control supply of electric power to the fixing unit,
• wherein the storage member includes an attachment part in which a supply container with a developer enclosed the supply container is attachable to and detachable from the attachment part, and
• wherein, with reference to a center of the heater in a longitudinal direction of the heater and in a case where an area on one side of the heater center is designated as a third area and the area on the other side of the heater center is designated as a fourth area, the attachment part is arranged in the third area and the first temperature detection unit is arranged in the fourth area.
