Abstract:
1. An image formation apparatus comprising: a charging unit for charging an image carrying member to a predetermined potential; an exposure unit for exposing said image carrying member in order to form an electrostatic latent image corresponding to image information signals from an external device onto said image carrying member charged by said charging unit; a developing unit for developing said electrostatic latent image on said image carrying member with a developing agent to form a developing agent image; a transfer unit for applying a transfer voltage onto a transfer member to transfer said developing agent image on said image carrying member onto a recording medium; a fixing unit comprising an output unit for outputting information related to the environment in which said image formation apparatus is disposed; and a control unit for providing a predetermined lowering period of temperature for reducing temperature at said fixing unit between a fixing operation for a recording medium on which a developing agent image corresponding to previous image information signals is transferred and a fixing operation for a recording medium on which a developing agent image corresponding to next image information signals has been transferred, wherein said control unit sets said predetermined lowering period of temperature based on information related to said environment which said output unit outputs, and wherein said control unit reduces temperature at said pressure member by stopping heating with said heating member during said predetermined lowering period of temperature.
