摘要： PROBLEM TO BE SOLVED: To solve a problem that, when a contact plate of a pressure member or a contact section of movement regulation means are stained with an electrical insulation material such as lubricant or toner, a situation that lubricant comes to an end of an operating life becomes unable to be detected because a conduction state is hard to be obtained even though the contact plate of the pressure member contacts with the contact section of the movement regulation means.SOLUTION: An image formation device comprises: detection electrodes 3 and 4 which detect an operation life of lubricant 78 and are capable of contacting with a conductive holder 2; and a regulation member 5 to regulate a displacement of lubricant 78 by a pressure member 1 in a direction that the lubricant 78 contacts with a brush roller 74. The operation life of the lubricant 78 can be detected when a relation between the holder 2 and the detection electrodes 3 and 4 is changed from a contact state (a conductive state) to a noncontact state (an insulation state) because the displacement of the lubricant 78 in the direction that the lubricant 78 contacts with the brush roller 74 is regulated by the regulation member 5.

摘要： PROBLEM TO BE SOLVED: To prevent waste toner equal to or more than tolerance from being fed into a temporary storage unit that is provided so as to continue image forming operation even in a state where a waste toner bottle is detached without providing a sensor in the temporary storage unit.SOLUTION: The image forming apparatus is configured such that discharge speed of the waste toner to be discharged from the temporary storage unit is higher than feed speed of the waste toner to be fed into the temporary storage unit. In the image forming apparatus, a storage counter counts driving time information of a body-side waste toner-conveying member that feeds the waste toner into the temporary storage unit when and after detecting detachment of the waste toner bottle (S41). When the counted value becomes a storage threshold (S44), it is determined as a full state of the temporary storage unit, and image forming operation is inhibited (S45).
