Abstract
A potential estimation apparatus estimates a potential of a photosensitive body of an image forming apparatus that carries out an electro-photography process using the photosensitive body. The potential estimation apparatus includes a sensor group for sensing and outputting data related to information which affects the electro-photography process, a storage unit for at least storing the data output from the sensor group and information related to charge of the photosensitive body, and an estimation circuit including a neural network for estimating a charged portion potential of the photosensitive body based on a charge retentivity of the photosensitive body learned by the neural network. The neural network in a learning mode receives at least one of the data output from the sensor group and time-sequentially sampled, and parameters which affect the charge retentivity of the photosensitive body as an input, and receives as a teaching value a charged portion potential which is obtained in advance with respect to at least an amount of charge and the charge retentivity of the photosensitive body.
