Abstract:
1. An image formation apparatus comprising: an image formation apparatus body; and a replacement member detachably provided in the image formation apparatus body and configured to be used for image formation, wherein the replacement member includes a first storage configured to store a life determination value used in a life determination of the replacement member, and the image formation apparatus body includes: a connection section configured to be connected to the first storage of the replacement member; and a controller configured to operate in: a first processing mode of accessing the first storage of the replacement member to acquire the life determination value and managing a life of the replacement member based on the acquired life determination value; and a second processing mode of managing the life of the replacement member such that a quality of image formation using the replacement member is higher than that obtained through an operation in the first processing mode, wherein the image formation apparatus body includes a second storage configured to store management information including the life determination value used in the life determination of the replacement member, when the controller fails to acquire the management information from the first storage of the replacement member, the controller sets the life determination value applied to the replacement member to the life determination value acquired from the second storage, the image formation apparatus body further includes an operation reception unit capable of receiving an operation from a user; and when the controller acquires the life determination value from the first storage of the replacement member, the controller starts operating in the second processing mode, uses the operation reception unit to receive an input of the life determination value, and sets the life determination value applied to the replacement member to the life determination value inputted from the user when the life determination value inputted from the user is smaller than the life determination value obtained from the first storage of the replacement member.
