A spark plug having a center electrode, an insulator and a metal shell and satisfying conditions (1) to (5) as defined herein. Also disclosed is a method of manufacturing a spark plug including the step of producing an insulator by preparing a raw material powder in such a manner that the particle size distribution ratio (90% volume diameter/10% volume diameter) between particles of 10% volume diameter and particles of 90% volume diameter in the raw material powder is 3.6 to 5.2, and then, press-forming and sintering the prepared raw material powder.

A spark plug (1) includes an insulator (2) and a metal shell (3), including a middle section (41) positioned between a collar section (16) and a tool engaging section (19). The middle section (41) has a bulged section (42), a first slender section (43) and a second slender section (44) that is the most slender at a portion positioned further to the leading end side than the bulged section (42). In a cross-section including the axis CL1, when the distance between both slender sections (43) and (44) along the axis CL1 is F (mm) and the bulged amount to the inside in diametrical direction of a most bulged section (42M) with respect to an imaginary line that connects a portion that is positioned furthest to the inside in diametrical direction of both slender sections 43 and 44 is G (mm), the relationship 0.00

A fixing device includes an endless belt and a belt holder contacting and rotatably supporting each lateral end of the endless belt in an axial direction thereof. A first protection ring and a second protection ring are interposed between the endless belt and the belt holder in the axial direction of the endless belt and rotatable in accordance with rotation of the endless belt to protect each lateral end of the endless belt as the endless belt is skewed in the axial direction thereof and brought into contact with the first protection ring. A friction coefficient between the first protection ring and the second protection ring is smaller than a friction coefficient between the first protection ring and the endless belt.

An image forming apparatus includes a fixing device. The fixing device includes a rotatable endless fixing member, a nip forming member arranged inside the fixing member, a pressing member in contact with the nip forming member via the fixing member, and a heating source configured to heat the fixing member. When an abnormality occurs in at least one of the fixing device and other devices included in the image forming apparatus, a rotation of the fixing member is stopped prior to stopping a rotation driving of a discharging unit and, after stopping, the fixing member is controlled to rotate.

A thermal printer includes a first thermal head, a first platen roller, first biasing means, a second thermal head, a second platen roller, and second biasing means. The first thermal head, the first platen roller, the first biasing means are in contact with a heat-sensitive layer of thermal recording paper. The second thermal head, the second platen roller, and the second biasing means are in contact with a heat-sensitive layer of the thermal recording paper. The second thermal head is arranged on the upstream side of the first thermal head in a paper feed direction. A paper feed speed of the first platen roller to the thermal recording paper is larger than a paper feed speed of the second platen roller. The first platen roller is in contact with the thermal recording paper while being more slippery compared with the second platen roller.
