Abstract

unidade de controle de temperatura para substrato fotocondutor eletrofotográfico é fornecida uma unidade de controle de temperatura para um substrato de fotocondutor eletrofotográfico contendo um elemento de membrana estirável o qual está liberavelmente disposto em um espaço oco do substrato cilíndrico, em que o elemento de membrana é configurado para estirar seqüencialmente até atingir a parte mais profunda do espaço oco do substrato cilíndrico como um resulta do da introdução de um refrigerante no mesmo para contatar intimamente toda a parede interna do substrato cilíndrico e retrair seqüencialmente para o formato original do mesmo como um resultado de liberação de refrigerante do mesmo, de modo que o elemento de membrana está liberavelmente disposto no espaço oco e em que o elemento de membrana é configurado para fazer uma transferência de calor entre uma superfície do substrato cilíndrico e o refrigerante via o contato íntimo do elemento de membrana com a superfície interna do substrato cilíndrico de modo a controlar a temperatura de superfície do substrato cilíndrico.
