Abstract:
A temperature control method of a heat developing apparatus comprising a heat processing section to conduct heat developing on a heated developing sheet on which a latent image by an exposure is formed, is opened toward outside of an apparatus by an opening and closing motion of an opening and closing cover, which comprises:first temperature detecting by a first sensor to be disposed in a vicinity of a conveying path of the heat developing sheet of the heat processing section and to be exposed to an outside of the apparatus when the opening and closing cover is opened; second temperature detecting, at the same time with the first temperature detecting by the first sensor, by a second sensor to be arranged in the heat processing section and to be kept unexposed to an outside of the apparatus when the opening and closing cover is opened; selecting an optimum combination of a control variable and a control amount from predetermined combinations of control variables and control amounts in correspondence with a combination of a result of the first temperature detection and a result of the second temperature detection; and controlling a temperature of the heat processing section based on the optimum combination of control variable and control amount, which is selected, at a time of the start of an apparatus operation.
