Abstract
A protective layer setting unit includes a protective agent and an application unit configured to apply the protective agent to an image carrying member in a manner sufficient to satisfy equations (1) and (2). A surface condition of the image carrying member is determined by an applied-agent amount index “X” and an agent coating ratio “Y,” and a ratio of “X/Y” is set to 0.020 or less after applying the protective agent for 120 minutes.applied-agent amount index X=Sb/Sa (1)agent coating ratio Y=(A0−A)/A0×100(%) (2).
